PS2 Model 30 memory

2017-01-26 Thread jim stephens
I have a friend who wants to add more memory to a PS2 model 30. They are 
off in the wilds of Oz and acquired this for a good price and would like 
to just upgrade it to run some programs they have which do not run on 
modern faster systems.


I know this is a snake pit to deal with, and can get more info if 
someone can get me some information or point me at references for them 
to look at.


What I'm really interested in doing is seeing if just the memory can be 
had, and it isn't easy to find Sim modules these days, though I suspect 
there are metric tons of them rotting in places forgotten and not 
recycled yet.


anyway any info to get started would be useful.

i see there are entire systems on epay, and may suggest just buying one 
of them and cannibalizing them for their memory should the asking price 
for the individual SIMM parts be ridiculous.  i could buy the system, us 
the system to be sure the memory does something and send them the 
memories alone for reasonable shipping.  It would also net them a backup 
hard drive which are very scarce in even good times as well.


I'm hoping that the memories were common to other systems and not some 
oddball special IBM part.  Old advertisements that show up on google 
show a number of people making them, but that doesn't mean they can be 
found now of course.


thanks

Are they different than plain 30 pin simm? I remember I had one of these,
had a 30 pin simm, used it as a keyholder, when first 386 boards appeared,
I sold it to use on a 386 for a hefty price! :oD

AFAIR, these are common 1mb 30 pin simm

I was afraid someone might say that. Whilst I don't have a memory map for
this system (or any other docs apart from the ones I'm writing myself) I did
notice last night that CAS-1 was missing. RAM is laid out like a CBM PET
with 16x 4116 DRAMs split into lower and upper blocks. RAS and CAS-0 are
pulsing.

More probing tonight then!

Pricey but looks nice, this seller has sold a lot of DEC gear lately.
11/35, etc.

My opinion..the 11/34 is an 11/40 without the aggrevation... and the lights.

I have owned a few, a great UNIBUS system and I regret not spending more
time on them when I had one...but for $5000, not that much regret.

I've run quad-RL02 systems before - kinda handy.  Usually the 4th one
is available for transfers between machines and not in use 100% of the
time...

Hmm... I've worked with a lot of 11/34 over the years but not 11/40.

The 11/34 is a great small-to-medium Unibus system.  In the full-sized
BA11-K, plenty of room for peripherals.  The only real limitation I
ever had was the 256K memory space (that's where the 11/24 comes in
handy - not faster but fatter).

It will be interesting to see if that price holds up to real-world demand.

 Odd.  This would imply you couldn't wind a tape past a medium error and 
read what's behind, but I surely did it a couple of times with DDS tapes. 

 And this is exactly why I gave up on some proprietary (OSF/1 IIRC) `dump' 
utility as it recorded an archive directory at the beginning making the 
whole archive unusable if an error developed there.  OTOH `tar' keeps file 
information along with actual data spreading it across the archive, so any 
medium error only causes the immediately affected file to be lost.  Same 
with `cpio' (except for the arcane CLI).

I find that the tar CLI in its full glory is no less arcane than the

Ah, but what is "the tar CLI"?  The POSIX one (which version?)?  The
GNU one (which version?)?  The V7 one?  The one you learnt 15 years ago
and have trouble remembering anything beyond even now? :-)

True - and true of a lot more than just tar.  And, if you are ready to
give up all the functionality correspnoding to the new options
(whichever set of new options you mean), it probably wouldn't be that
hard to tweak an old tar source into building today.  _Also_ true of a

Price is steep indeed, my guess a grand for the system (if fully working)
would be a more realistic price, but that's just my opinion.

I have 2 11/34's, one in the 5.25 inch box, and one in a BA11-K box,
I also have an 11/40 in need of some minor repair.

For the NCAR Mass Storage System, when we upgraded our tape drives to Sun STK 
T1 models, we lost the ability to skip past the EOT mark with standard 
firmware.  We asked Sun to provide a firmware modification that let us issue 
four or so reads after reaching the EOT mark, and the drive would then continue 
on until it found good data again.  We didn’t need it very often, but it was 
handy to recover single copy data.

$1000 isn't realistic at all. It should definitely be higher than that.

Oh, and thus fully outfitted to run RSTS (likely the appropriate memory and

Of course it all depends on what buyer decides they want it, as "worth" and

I'm actually surprised that it would be worth that much.
Moving RL02's is easy, just make sure the heads are locked by moving
the little metal plate next to the heads (and undo it after relocation
is done).

Re: Looking to read past EOT on DDS/DLT/LTO

Hi,

Thanks for the notes/comments/suggestions.

Recovery service: not that I've found.  Most of the ones I know of have *us*
as their HP 3000 experts (i.e., we help them :) ... when I've asked in
recent years
about handling damaged or overwritten DDS (or newer) tapes, I've always been 
told 'no'.

The "cut out some tape" would definitely not work.  At least LTO, probably DLT,
have multiple tracks and the tape makes multiple passes from start of tape to 
end of
tape as it writes the entire tape.  That means on a 16 track tape, you'd lose 
part
of 16 different sections if you cut out a piece of tape (ignoring the question 
of whether
or not the drive could resynch after such an error :)

Eric's reply is closest to home ... that's why I mentioned a 'hacked' drive,
hoping someone might know specialists who have one.

Chuck mentioned an approach I had mentioned: the power kill during writing 
approach.
I'm hesitant to try that as it will (based on dim memory of doing it 15 years 
ago
on a DDS) lose a small bit of data ... if it works at all.

I'm giving up for now.

thanks,

Stan

I concur.

My methodology for _accurately_ valuing something like this is to create as
comprhensive a list of sub-items as possible, then value them, and then add
it up; something like this:

$A  Bare H960
$B  2 x H960 side panels
$C  BA11-K (box and power supply)
$D  BA11-K slides
$E  DD11-PK backplane
$F  PDP-11/34 CPU boards
$G  MS11-L
$H  4 x RL02 drives
$I  15 x RL02 packs

etc etc. Alas, the listing doesn't say exactly which boards are in the 11/34
(and not even any pictures of the insides). I don't know exactly how much $A,
etc are - I have varying levels of experience with these things, but for
instance, I know that MS11-L's are much desired, and command high prices.

Note that the listing does have a reserve, so their actual asking price is
above $5K. Getting that total out of one bidder may be a bit too far; they
might have better luck getting it sold if it was a couple of smaller
lots.

That's a good point.  Can it really be true that a tape error that creates a

I concur.

My methodology for _accurately_ valuing something like this is to create as
comprhensive a list of sub-items as possible, then value them, and then add
it up; something like this:

$A  Bare H960
$B  2 x H960 side panels
$C  BA11-K (box and power supply)
$D  BA11-K slides
$E  DD11-PK backplane
$F  PDP-11/34 CPU boards
$G  MS11-L
$H  4 x RL02 drives
$I  15 x RL02 packs

etc etc. Alas, the listing doesn't say exactly which boards are in the 11/34
(and not even any pictures of the insides). I don't know exactly how much $A,
etc are - I have varying levels of experience with these things, but for
instance, I know that MS11-L's are much desired, and command high prices.

Note that the listing does have a reserve, so their actual asking price is
above $5K. Getting that total out of one bidder may be a bit too far; they
might have better luck getting it sold if it was a couple of smaller
lots.

Noel
I've dealt with this seller.  He is probably willing to tell you what 
his reserve is, and let you put in an offer.  if it doesn't sell he 
wants to move stuff out, not look at it anymore, and a $5k bid might 
take it, or he would tell you his reserve.


Mind that he has sold and has a lot of stock and probably has better 
market knowledge right now, so he might hold out, or might surprise you.


Also note that the "pick it up in NJ" makes it less desirable, so a good 
offer and ability to quickly get it out of his way will help too.


I've bought select boards, and he was diligent in getting me what I 
needed for one.


I'd love this system if I had the $$, moving capability.  If I were to 
run actual hardware it is hard to argue with a loaded RSTS system 
already spinning.

DECUS TECO for OS/8

2017-01-26 Thread Charles Dickman
I am trying to build the DECUS TECO with VT support for OS/8.

TECO came from ibiblio and the assembler listing says it is OS/8 TECO
VERSION 7. I am using MACREL-V1B. It all assembles without error, but
the linker fails with a NO ROOM message.

I can't find any information on what NO ROOM means from the MACREL
documentation.

This is using SIMH PDP8 with 32k words.

I also found MACREL V2 source, but it in in MACREL, but I have not
tried to bootstrap it using V1.

I was hoping to make source editing just a little bit easier.

That's certainly more convincing, but it still seems to be a bit of a
mystery.

The four authors of IBM's Early Computers were all engineers and
engineering managers intimately involved with the development of the
computers in that time frame, were researchers at IBM when the book was
written, and based much of the book on material from IBM archives.  I could
imagine them getting a date wrong, but it seems pretty surprising that they
would specifically claim that the 7070 was announced far before the 7090
but shipped six months after, if that wasn't true.

IBM generally didn't consider a data processing system to have "shipped"
until it passed the field acceptance criteria, e.g., assembled on-site and
passed diagnostics. Perhaps the 7070 didn't pass acceptance testing until
April 1960?

Here's a catalog page and pic of the Northern Scientific NS-544 from 1967/8, I 
wonder if the NS-600 might be a subsequent model:

https://books.google.ca/books?id=25-jBQAAQBAJ&pg=PA716&lpg=PA716

This is billed as a Digital Memory Oscilloscope.
It sounds like a contemporary of and very similar to the HP5480 Digital Signal 
Analyser I have, from the same era.

The NS-544 and HP5480 are basically precursors to the modern DSO, but rather 
than being intended as a general purpose scope (too slow and too expensive),
they had modes and were targeted for applications that could benefit from the 
digitisation and (numerical) storage and manipulation of the signal.
They could do things like signal averaging and very-slow-signal capture. The 
HP-5480 had a mode which which would produce histograms of pulse rates (think 
nuclear decay rates).

So they contain AD converters, digital memory (core can be expected as Bill 
mentioned, if it's from the late 60s, that's what's in my HP5480), adder/ALU, 
and a whack of hardwired logic to control it all.

Pic of the front panel controls would be interesting and might help categorize 
it.

What are you trying to do with TECO?
I have a OS/8 RK05 image with MACREL and the TECO source that builds 
correctly. Or, did at some point.

Does IBM retain a corporate archivist on staff?  That might be a resource.

I do get the idea that the 7070, designed as a replacement for the 650,
was a machine that IBM probably would like to forget.

I would like a bit easier way to edit and EDIT and was hoping the VT support
made the learning curve less steep. The sources say VT100 and VT52,
and if am thinking that means VT52 emulation on a VT100.

Agreed.  $1000 is low for this system.  Prices on empty complete H960
cabinets have gone up over the years, even if the 11/34 isn't the most
"valuable" CPU in the line.

Then go price 4 BC20J cables and a terminator...

I'd certainly say this machine should support at least $3K price.
