2.9.1 BSD on 11/34 + sc21-bm + fujitsu m2333k

Exciting stuff for a Friday night, right?  Here's a visual aid in case

https://www.instagram.com/p/_K-zHhHvLn78Qu5ijWqMf-HBem1LKMLaEdI1c0/  The
M2333K is the smaller one on the left with the green and yellow lights on.
I'm booting from rl0, which contains the tuhs 2.9.1 rl02 image I wrote with
vtserver earlier.

I want to use my nice, roomy smd disk so I can pull in all the sources and
recompile stuff and I've managed to get this *so* close to working but I'm
getting

xp0a: hard error bn  cs2=1100  er1=0

on every single block when I try to mkfs /dev/xp0a 4800

This disk was working fine years ago via MSCP attached to the 11/73 (before
I lost the Micro/11 power supply).

Anyway, I referred to
http://bitsavers.trailing-edge.com/pdf/emulex/SC2151001-CC_SC21tech_Jan87.pdf
to set the emulation on the Emulex card for two rm03s and they're showing
up in xxdp's zrmlb1 formatter, though they won't format there, screensful
of errors.

I think I set the m2333k to 32 sectors, per this manual:
http://manx.classiccmp.org/collections/antonio/chrisq/B03P-4760-0101A_-_M2331,M2333_Micro-Disk_Drives_OEM_Manual.pdf

Because XXDP is reputed to be really strict, I figured that was normal and
then tried the Emulex on-board formatting procedure against both xp0 and
xp4 and they formatted perfectly without error.  Guess the Emulex on-board
stuff doesn't bother verifying much?

So I think that maybe I've misunderstood the hard sectoring / sector sizing
thing.  Does anyone remember the gist of it and would you be able to
describe?  Do you see any other mistakes?

I'm not an expert with SMD drives and I've never used your particular 
controller (I have a slightly newer Emulex in my 11/44) but here's a 
couple of things I noted while leafing through the SC21 manual you linked:


1.) The SC21's format does *no* verification at all.  It lays down an 
initial format and that's it.  It doesn't create the bad-block list 
(more on that later).
2.) Section 6 of the manual lists a set of modifications (patches) that 
need to be made to XXDP diagnostics in order for them to work properly 
with the SC21.  This includes the ZRMAC0 formatter form RM02/RM03.  
You'll likely need to apply them; hopefully you can find the required 
versions to hack...
3.)  In addition to setting the sector size/sector count on the Fujitsu, 
did you also configure the SC21 for the appropriate drive? (see Appendix 
A)  I don't see an M2333 listed there specifically, but there might be 
something with a similar (or identical) geometry you can use instead.


Regarding the bad-block list:  You are going to need this to be 
generated properly, and the only way to do that is to run the 
appropriate XXDP formatter and exercisers.  If you have the bad block 
list for the drive, hopefully one of the diags will let you enter it, 
otherwise I suggest running *many* passes of the exercisers until they 
stop finding bad blocks.


After you have that step done, you will need to have a 2.9.1BSD kernel 
that's been compiled with bad block support, otherwise BSD will simply 
ignore bad sectors and assume the whole disk is good -- which will cause 
bad things to happen as soon as something is written over a bad sector.


(Apologies if any of the above is already old-hat; just trying to cover 
all the bases I know of...)

I can't help you with M2333K specifics, but do you get anything
meaningful if you use 'dd' on the raw disk, first to read, then to
write?

ISTR /dev/xp0c or /dev/xp0g might be the "all the disk" partition.  It
doesn't really matter _which_ partition you are trying to read from,
but might as well start at the beginning and allow it to go to the
end.

If you can't read a block at the OS level, you probably won't be able
to write it to drop a filesystem on it (I'm sure there are imaginable
scenarios where that's possible, but for a simple smoke test, just try
to read one block with dd and pipe it to 'od'.  I can't remember if od
is available on 2BSD, but dd is most likely there since I think I
remember using it to stuff bootblocks at the fronts of disks).  Of
course there are several imaginable scenarios where you could read but
not write.  Write but not read is far, far less conceivable.

Oh! OK. New one on me, and I thought I was reasonable at US idioms. I

First editor. Hmm. I guess the Commodore full-screen BASIC code editor
on the PET series doesn't really count. But before I used it in any
anger, in Comp Sci class, I got a ZX Spectrum after playing with my
uncle's ZX 81. But the Spectrum barely had an editor, either, so I
mostly used Beta BASIC which was slightly (slightly) richer. (A used
Spectrum 48K cost my parents £80. No idea of exchange rates in
1982-1983: at a total guess ITRO US$ 140-150? That was the most
computer we could afford.)

First actual discrete editor which could load and save files was
probably EDT on a terminal on the University VAX in about 1985. I was
never a master but I could use it. Does that have enough early-editor
kudos? Probably not. :-(

When I started in 1969, displays certainly were not commonplace, but we got 
the jobs done anyhow.
All our (administrative) jobs started as punched cards (later data-entry on 
IBM 3740), were read via an IBM 2540 card reader / puncher, handled on an 
IBM 360/40, with output on e.g. the venerable 1403 printer. Data was kept on 
magnetic tapes and 2311 harddisks, with each a whopping 7.25 MB capacity.
So, when you had to look at something, you looked at fanfold paper, with 
holes on both sides.
Other applications could put holes in cards

graphics!

Instead of a screen, you looked at "paper" (a flat, thin, slightly 
flexible product made form ground-up dead trees).
There was a campaign called "The Paperless Office" set up by the 
papermills to sell more paper, by claiming that xerox machines, and using
fax machines instead of post office, would "save paper" (actually intended 
to "save paper industry")


Sometimes, it was non-simultaneously interactive, using a device called a 
TTY.  You typed in a command, and it did it, and then it typed its answer.

PI
SYNTAX ERROR
PRINT PI
0
PRINT 2 + 2
4
or

DOWN
YOU DON'T FIT THROUGH A TWO INCH SLIT
and
N
YOU ARE IN A MAZE OF TWISTY LITTLE PASSAGES ALL ALIKE

Sometimes, it was printed reports.  A thick fan-fold pile of continuous 
form paper that listed all of your SYNTAX ERRORs
Sometimes, it was special forms (also fanfold continuous), such as your 
paycheck.


Sometimes, it was a deck of punched cards.  (They are "PUNCHED cards", not 
"PUNCH cards", once there are some holes in 'em - "PUNCH card" can only 
mean blank cards to feed the PUNCH with).  Those went into drawer in a 
room full of special file cabinets, or into the input of another machine, 
such as a different machine such as "accounting machine" (which was used 
as a dedicated printer), or the card reader of another computer.  Inter 
computer communication was handled by a "gofer" carrying, or pushing a 
cart full of, decks of punch cards.  Each deck of cards, if less than 2000 
in a box, was inadequately secured with rubber bands and had diagonal 
lines made with magic markers, to recognize the rearrangements after the 
deck or box got dropped.  That process was later upgraded to 
"sneaker-net".


Sometimes, it was a reel of tape.  Used in similar ways to punched cards, 
except that the storage room was called a "tape library", and other than a 
tape number, and maybe owner's name, there weren't any diagonal lines 
across them.  There were "tape hangers" that wrapped around the outside of 
the reel, and small plastic "rubber" rings near the hub called "write 
rings".  The tape drives were the iconic image that filmmakers used 
instead of computers, which "don't look like a computer".


Sometimes, it was a big picture!  Take the deck of cards or tape to 
another machine that was dedicated to operating a "PLODDER".  It would be 
a large table, or a lorge roller (and since late 1960s sometimes a machine 
that wrote to 16mm or 35mm film!).  The plodder moved "pids" (rapidograph 
like pens) around, responding to commands summarized as N, S, E, W, UP, 
DOWN (oft subverted into manufacturer proprietary commands).  Large 
libraries of subroutines would convert into those primitives from commands 
such as LINE, CIRCLE, GRID, PLOT xxx V yyy.


Sometimes, the owner of some small machines, or the paid operator of some 
larger machines, would have a "FRONT PANEL", that was full of 
blinkenlights.  When the operator wasn't feeding the printers (trying to 
start a new box of paper without turning off the printer), they could 
stare at those lights.  Occasionally, an operator might start 
screaming or giggling uncontrollably when the computer told them a 
good joke, such as program counter repeating itself.


Sometimes, they controlled dedicated equipment (such as looms, milling 
machines, spaceships, etc.)


RARELY, there was voice output.  A quarter of a century ago, I had a 
friend who used a VOTRAX.  She had a laptop with a big gaping hole where a 
screen had once been. The first email that she sent me (she believed 
that the proper quoting was "NO QUOTES!"), said:

WINDOWS SUCKS
MOSAIC SUCKS
CAN I BORROW AN AXE?

Like her, if you know what you are doing, you do not need a screen.

Well, in the 1960's lots of companies ran their payroll, 
billing and general ledger on IBM 1401 and similar 
machines.  IBM sold 12000 of them, and then there were 
additional partially compatible machines in the same line 
(1410, 1460).  Many 1401's were used in the beginning 
entirely from cards, or cards and tape, with no disk.


Certainly, some people used them for math problems, as 
well.  I know our local phone company had a 1401 in their 
planning department, and they used it to compile statistical 
info telling them what equipment they needed to plan in the 
future.


Our University had a 1401 for accounting, and a 7094 for the 
rest of the University's needs.  Then, in 1969 they upgraded 
the 7094 to a 360/50.  None of these machines had 
"screens".  All programming was done on punch cards, most of 
the data was prepared on punch cards, although some came on 
tape.  Then, if you were a user with privileges, you could 
get some tiny amount of disk space to hold data for a while.
Sometime later, maybe around 1971 they got some IBM 2741 
terminals which were Selectric typewriters connected to an 
interface.  Later they got some IBM 2260's, which were 
Zenith 9" TV sets and a keyboard connected to an interface 
box in the machine room.  Very primitive, but very 
interactive, great for quick program editing and submission.

This disk was working fine years ago via MSCP attached to the 11/73

I lost the Micro/11 power supply).

Anyway, I referred to
http://bitsavers.trailing-edge.com/pdf/emulex/SC2151001-CC_SC21tech_Jan87.pdf 

to set the emulation on the Emulex card for two rm03s and they're

I think I set the m2333k to 32 sectors, per this manual:

Because XXDP is reputed to be really strict, I figured that was 
normal and

then tried the Emulex on-board formatting procedure against both xp0 and
xp4 and they formatted perfectly without error.  Guess the Emulex 
on-board

stuff doesn't bother verifying much?

So I think that maybe I've misunderstood the hard sectoring / sector

thing.  Does anyone remember the gist of it and would you be able to
describe?  Do you see any other mistakes?

I'm not an expert with SMD drives and I've never used your particular 
controller (I have a slightly newer Emulex in my 11/44) but here's a 
couple of things I noted while leafing through the SC21 manual you 
linked:


1.) The SC21's format does *no* verification at all.  It lays down an 
initial format and that's it.  It doesn't create the bad-block list 
(more on that later).
2.) Section 6 of the manual lists a set of modifications (patches) 
that need to be made to XXDP diagnostics in order for them to work 
properly with the SC21.  This includes the ZRMAC0 formatter form 
RM02/RM03.  You'll likely need to apply them; hopefully you can find 
the required versions to hack...
3.)  In addition to setting the sector size/sector count on the 
Fujitsu, did you also configure the SC21 for the appropriate drive? 
(see Appendix A)  I don't see an M2333 listed there specifically, but 
there might be something with a similar (or identical) geometry you 
can use instead.


Regarding the bad-block list:  You are going to need this to be 
generated properly, and the only way to do that is to run the 
appropriate XXDP formatter and exercisers.  If you have the bad block 
list for the drive, hopefully one of the diags will let you enter it, 
otherwise I suggest running *many* passes of the exercisers until they 
stop finding bad blocks.


After you have that step done, you will need to have a 2.9.1BSD kernel 
that's been compiled with bad block support, otherwise BSD will simply 
ignore bad sectors and assume the whole disk is good -- which will 
cause bad things to happen as soon as something is written over a bad 
sector.


(Apologies if any of the above is already old-hat; just trying to 
cover all the bases I know of...)


- Josh


I'll also add that in order to create a filesystem on the new disk using 
mkfs, you'll need to have run the 2.9BSD 'disklabel' program on it to 
create the disk label (partition map).  You can do this via vtserver, 
it's covered in the manual.  Obviously this can only happen after you've 
managed to format/exercise the disk :).

Re: Display-less computing was Re: TOP POSTING

2015-12-12 Thread Robert Rissell
Mike,

One of the key manners of getting information processed was batch jobs run
by the computer staff.You never see the computer at all.

Individual programs (usually one at a time - using the whole machine for
one program) were loaded, pointed at input files, run and then unloaded
with the
output file or a printout as the end result.

Some of the batch jobs did such tasks as:

Sorting the input file
Adding account information to a ledger in a bank
Calculating what is going to happen in a simulated physics problem
Calculating trajectories of artillery shells
Calculating Averages, Means and Standard Deviations of Statistical data
Generating form letters based on an input list of names and addresses and
printing them out
etc.

The batch job consisted of a Batch Number for accounting, the keyword-coded
header card(s) to tell the computer what to do with the following cards
such as Compile, Link, Execute then Output for a Fortran source.Any
options are read in from the input file or set in the source file.   This
was often
done by preparing stacks of cards with the input or control options and
putting them in with the source deck.   Then there was a card indicating
the end
of the source file.Following the source you would find the cards
listing the input for the program, such as a list of accounts and amounts
to be added
together or sorted.  Last you would find a specially punched control card
to indicate the end of the batch job card deck.

The total amount of CPU time taken to accomplish the batch job would be
tracked and printed out for accounting at a rate per CPU second.   This rate
could vary based on priority or time of day.   So it was in your best
interest to write efficient programs.Your source and input deck was
returned to
you in a cardboard tray together with any resultant punched cards, paper
tape or printouts (usually on fan-fold paper).   If there was an error
during the run,
any error messages are returned to you for resolution.   Error messages
were usually in English, but your output could just be a stream of numbers,
letters
or sometimes a printed out graph or picture, line by line.

What the computer did as a job was hopefully something that was not easier
done by hand.

You COULD read the holes, if you really HAD to.  Keypunches 
printed the alphanumeric form on the top edge of the cards.  
if you punched a deck of cards on the CPU's card punch, 
there was no printing.  If it was an "object deck" ie. 
binary code, you would never "interpret" the deck.  But, if 
it had something that might be human readable, there was a

Yes.

If you dealt with the cards long enough, or consciously tried to, you 
learned the punch patterns.  They were not complicated.

or
you could make a printout
or
you could feed the cards through an INTERPRETER, which printed the card 
content on the card.  The usual INTERPRETER used a larger font, and only 
printed 60? of the columns.  If you had unusual needs for which columns to 
print, or wanted to rearrange, etc., then you could program it with a 
plug-board.  You kept some of those plug-boards around for specific tasks. 
For many years, I kept around a plug-board labelled "COBOL INTERPRETER", 
just to prove that a COBOL interpreter was possible :-)
There was also a sb-model of the 029 punch series that was a 
"punch/interpreter".  It could take a card, or a deck thereof, and print 
the content of the card along the top.  It had a significant advantage 
over the INTERPRETER in that it printed 80 columns, aligned with the 
columns of punches in the card.


On "normal" cards (not round-hole, system3, film-window, etc.), there were 
80 columns (numbered 1-80), and 12 rows (X,Y,and 0 through 9).

[When I die, bury my remains face down, 9 edge first]
Text was encoded with a punch in Y, X, or 0 plus a punch in 1 through 9.
Special characters and punctuation were other combinations.  Lower case 
was generally not used.
Other punch combinations were possible, and occasionally used, such as raw 
binary codes.  Punching out all punches in a column or columns created a 
"lace card", which wasn't liked by the reader.
"/*" in the first two columns had special meaning for 360 JCL, which 
required some extra care when attempting C compilers.





on the fan fold paper also was it in code or just plane English?
Only in the aerospace industry would you find people who spoke in plane 
english.  Everybody else preferred it "plain".

I'll probably be looking for a new home for one of the three working

I have close friend that related a story to me the other day.

In his younger days he worked for a military contractor that
manufactured inertial reference systems for military aircraft.

They used a bare naked PDP-11 (just lights and switches) as part of
final acceptance test. Over the years, he got quite adept and
manipulating the switches and reading the lights during the four hour test.

One day a government auditor noticed that he was performing the final
test impossibly faster than the 'standard' amount of time and concluded
that he was not testing the unit per the procedure and that the big
defense company was in violation of their government contract. To say
this was a *big* deal is an understatement.

When he was called to the plant manager's office, he offered to prove
that he was following the test procedure to the auditor and anyone else.

The first attempt to demonstrate the test procedure was a complete bust.
Every time he manipulated the switches or read the lights, the auditor
would interrupt him so that he could compare the front panel switches
and lights to the test procedure. He could not do the test with the
constant interruptions - he'd get lost and confused. Now he was getting
a little scared.

He finally convinced the auditor to video tape the final test procedure
so that he could perform it uninterrupted. He, the plant manager, and
the auditor reviewed the video tape - pausing the tape as necessary -
and concluded that he actually did perform the test procedure as required.

He mentioned that manipulating the switches was committed to muscle
memory and it was like playing the piano.

As a reward for his efficiency, the auditor attempted to reduce the
'standard' amount of time for the product - thus reducing the amount of
money that the government would pay the contractor for the service.
After all, if he could perform the test that fast - anybody could...

mountaintop with Cray stuff. It's so heavy and no permanant place for it 
so these days I prefer it when I can put 3 systems into a plastic tub.


I'm involved with a music and gaming festival (the music is mostly video 
game music) and we've spawned a computer museum as a come-back side 
project. This year I think there was about 32 to 34 systems out which 
include classic Macintosh stuff (Something personally I'm not a fan of 
outside of the case designs), a NeXT, some Atari ST, Atari 8 bit, Color 
Computer 2 or 3, Apple II, Apple IIGS, 8088 IBM PC, 80286, 80386, 80486. I 
think Mike had 2 of the later PCs (the 486es) on thinnet running Doom over 
IPX/SPX.


Next year the computer museum space is around 3000 square feet and I think 
they're going to bring more like 100 to 120 machines (not sure.) I've 
offered them my Octane, Indigo, NeXT, Sun Voyager, Atari Mega 2, Atari 
520ST (need a mouse), Atari TT030 (need a mouse), Amiga 500, (probably 
hold bcak Amiga 600 it's so small it makes me nervous), C64, Dolch PAC 
luggable PC w/ Gravis Ultrasound, and some other stuff. Gave away the 
Model 4 TRS-80 but it should be coming. They've got a lot of the plastic 
microcomputer stuff covered until you hit fringe stuff like Mattel 
Aquarius and import machines. I did meet locals that import Russian and 
other MSX clones but don't have solid enough contact information to get 
any of it (might need to run an inverter to generate 50hz power and PAL 
TVs for that stuff.)


Friends have all sorts of stuff, and some things might be coming like a 
X68000 (for the Castlevania fans :-) and MSX and other fun things.


Anyways, where was I. Oh yea. Much love for the Micros, but different 
people came up at different times. My only CPM box is a beautiful IMSAI 
8080 -- which I keep covered. Still building the S100 CF card.

Mike, here's another piece of mailing list netiquette that I think has
been mentioned recently but only briefly: when you start a new topic,
please do so by sending a brand-new email to cctalk@classiccmp.org
instead of replying to an existing message. Your question about what
earlier computers were like was a good one that brought up some
interesting responses, but I fear those messages got ignored by people
because they were still shown as replies to this neverending top posting
thread (most of which anyone would be 100% justified in throwing in the
trash without reading).

Sending a new email to start threads not only gives you a good chance to
write a subject line that actually describes what you're saying, but it
causes decent mail clients to not link the message with earlier ones on
another topic. Different email readers do that in different ways -- some
just treat any messages with the same subject line as a thread, while
some (like mutt, which I use) are happy to ignore subject lines and just
go by the reference field in the emails' headers (a field which is often
hidden from view).

So, by all means, start new discussions. But make sure they're treated
as new by emailing cctalk@classiccmp.org directly instead of replying.

Yes, I was deliberately conflating two disparate meanings of the word. 
When a friend was discussing compilers V interpreters, I pointed to the 
plug-board, and said, "SEE! There IS a COBOL interpreter!"


The board was itself not a COBOL interpreter, nor even intended to be 
labelled as such.  The ladelling was intended to identify that it was a 
plug-board FOR the Interpreter (not BEING an interpeter), and that it was 
plug-wire programmed for doing decks of cards containing COBOL code. 
"COBOL" and "INTERPRETER" should have been two separate labels. I kept the 
board around for years, just for the sake of making that ridiculous 
misinterpretation.



I don't know where it is now.  After I retired (after 30 years), I took

I had also been promised verbally a month to forward content from my email

The plug board could control which columns of the punch card appeared in
which columns of the printout; it served as a simple FORMAT program. The
COBOL interpreter plugboard rearranged the COBOL source on the punch card
to a more readable style on the printer.

CBM 1541 drive faults

2015-12-12 Thread Jules Richardson


I have four 1541's now, two of which seem to init OK, and two of which sit 
there with the drive spindle constantly spinning and the access LEDs lit, 
the latter behavior which I believe indicates a multitude of possible 
microcontroller-related faults...


I've done the obvious, reseating socketed ICs, checking the +12V and +5 
rails, and checking the on-board CPU reset line. Does anyone have any tips 
for what's best to try next?


I read somewhere that ROM faults aren't unheard of, ditto with 6522 VIA 
failures. Also the 74ls14 at UA1 (particularly if someone's unplugged the 
drive from the host with power on), but I think that affects CPU reset, 
which appears to be working in my units.


(is the firmware interchangeable between different board revisions? i.e. 
can I swap in firmware from one of the drives that appear to init OK to 
rule that out as a fault, or do I have to worry about matching PCB revisions?)


Also, has there been a worse external drive in the history of floppy 
storage? Slow, complicated, expensive and unreliable seems to have most 
bases covered ;-)

Exactly.
That's why there was a plug-board kept around on a shelf preprogrammed for 
the desired formatting for COBOL programs.
However, being for an "INTERPRETER", not a "407 ACCOUNTING MACHINE" (used 
for generating printouts from decks of cards), the plug-board controlled 
the column positions where the material was printed on the card, not 
printout.

Hmmm, that could be the issue.  I remember (and even have code IF-ed 
out) to do ATA sans interrupt and it would run into problems.  I found 
that waiting for the interrupt to hit fixed the instability.  Granted, 
this was in simple x86 code, but if I didn't have to put the ISR code 
in, I wouldn't have done it--as it it makes things a bit more complicated.


FWIW, I can pass you the code I was using circa 1999.  It might shed

I entered university on the tail end of the batch era, and for student 
coursework that was the way it worked: job control cards, source, data.
Compile, list, execute, program-output all in one submission.

(This was under MTS, which despite being a timesharing system (Michigan 
Terminal System), still had support for batch.)

The good thing about batch is there was always the incentive to get your entire 
program right the first time.

To me, that's a hint at best. If it had been a winking face, I would
have been pretty confident that humor or irony was intended; simple
smiling emoticons don't indicate irony to me.

Re: CBM 1541 drive faults

I have four 1541's now, two of which seem to init OK, and two of which

I've done the obvious, reseating socketed ICs, checking the +12V and 
+5 rails, and checking the on-board CPU reset line. Does anyone have 
any tips for what's best to try next?


Locked on LEDs and spindle motor would suggest VIA to me, though it's 
been many years since I've looked at one. First thing I'd check is that 
there's activity on the address/data buses. If things are going on, and 
there are 6522s at hand, I'd try a quick swap.


I read somewhere that ROM faults aren't unheard of, ditto with 6522 
VIA failures. Also the 74ls14 at UA1 (particularly if someone's 
unplugged the drive from the host with power on), but I think that 
affects CPU reset, which appears to be working in my units.


Can you swap ROMs in from one of the booting drives? Worth a go, though 
I've never seen a ROM failure.


(is the firmware interchangeable between different board revisions? 
i.e. can I swap in firmware from one of the drives that appear to init 
OK to rule that out as a fault, or do I have to worry about matching 
PCB revisions?)


I wouldn't have thought it'd matter, though maybe the 1541 II was 
different enough.


Also, has there been a worse external drive in the history of floppy 
storage? Slow, complicated, expensive and unreliable seems to have 
most bases covered ;-)


I sort of agree, though I have to say that of my pile of about 30 1541s 
and 1541 IIs, all but two ran up fine on first test, after having been 
in storage for 25 years. One had a bad 6522, and the other had an 
alignment issue. They were all still amazingly slow though!

I'm reading about those terminals and find it just fascinating how they
used acoustic delay line memory to remember the pixels. But I have lots
of questions:

1. Did the cables connecting the 2260s to the display controller
actually contain the delay lines themselves, over the whole length; or
were the delay lines just inside the controller and then some electronic
signal was sent out to the terminals?

2. I would think that the wave travelling along the delay line would
weaken over time. How was it refreshed?

3. What kind of speed could be acheived, and did this depend on the
number of connected terminals?

VAX 4000-200 Battery Location/Removal Question

2015-12-12 Thread Bob Vines
Since I've fallen _way_ behind in reading my email (I'm reading July 2015's
messages now), I've just recently read a thread where removing the
batteries from VAX 4000-xxx systems was discussed and recommended.

Since I didn't get _any_ documentation when I rescued my VAX 4000-200
system, which module(s) contain batteries that I should remove for safety?
Or can you recommend the appropriate manual(s) at sites like Bitsavers that
I download & study to locate to the batteries to remove before they leak
and cause corrosion issues?

Hopefully I don't already have a big mess to clean up!


Thanks,

Bob

The delay lines were only within the 2848 control unit. From the
descriptions by others on the list, the 2260 displays were completely
dumb, and would display whatever was sent to them if I'm reading
things correctly.

Once the signal reached the end of the delay line it was sensed,
regenerated and put back into the delay line, while also being
converted to scanlines to be sent to the 2260. Similar to the mercury
delay line memories of older machines like the UNIVAC, or EDSAC.
Though the 2848's delay lines were wire based not long mercury tanks.

You can most likely find that information in a manual. I think that
the A27-2700 manual will have it, located on BitSavers, of course:



Not an expert, just someone with some itnerest in it.

Re: IBM 2260 acoustic delay line

The IBM 2848, the control unit for the 2260 terminals, contained
mercury (!) delay line for the video memory. There may have been some
compensation for the transmission to the terminal, but I have have not
seen the technical details - I think it was not a concern, probably.

Line loss is really not a problem. It might have been if the lines
were miles long, but in typical installations, that was not anywhere
near a problem.

As for speed - not an issue for basically baseband video.

I'm reading about those terminals and find it just fascinating how they
used acoustic delay line memory to remember the pixels. But I have lots
of questions:

1. Did the cables connecting the 2260s to the display controller
actually contain the delay lines themselves, over the whole length; or

I would assume it makes no sense to have it in the cable. It is acoustic not 
electronic.
Typically it would be a loop. Data and possibly clock goes in one end. At the 
other
end would be a preamp and recovery circuit. It would then be gated with 
possible new updated data and sent down the delay line again.
