I was born too late to see the SR-71 fly. I could still see a U-2 fly
though (those are also neat planes). There's so many cool planes, and
so little time to experience them all. (SR-71/A-12, U-2, B-52, CF-105,
Avro Lancaster, Supermarine Spitfire, Hawker Hurricane, Messerschmitt
Bf 109, Avro Vulcan, Antonov An-225, Concorde, Mitsubishi A6M Zero,

NASA attempted to keep one airframe (don't recall which one) flying for 
research.  The effort didn't last long, however.


I got involved in an interesting way.  A friend who sold tape drive 
parts for Kennedy and for CDC as well as SCSI drives of various types 
had a company called Fintec in Laguna Hills, Ca.  Right off the approach 
to El Toro which was still flying, FWIW. Visits were always great when 
the Marines were flying.


Anyway, he specialized later to try to keep a business going as the 
drive business wound down selling various adapters.  One he had come 
across was a device made in Great Britain which would present a 
formatted Pertec tape interface to a host and allow one to run a SCSI 
drive on the other side.


He had gotten a call for an application which puzzled him, as he didn't 
know a lot beyond the basics, so I got invited to a meeting with his 
potential client.  Turned out that a fellow in a white shirt and tie, 
missing only the pocket protector showed up and was from a firm in Burbank.


the SR71 turns out didn't have a lot of gear on board to tell directly 
where it had been other than basic instruments, and what it did was 
record a lot of data in some onboard electronics.  Once it landed from 
one of its original missions you had a pile of exposed film on board, 
and the information of where you'd been at mach 3 in the computer.


One of the many support systems you had to have to make an SR71 happy 
was a couple of 10' or so containers.  One had the gear to plug into the 
airframe and transcribe the information to a tape (luckily it was a 
Pertec formatted drive, or at least his customers was).  Once the 
information played out of the airframe and was on the tape, the tape was 
taken to a Vac 7xx of some sort in the other container which was up and 
running by then, and a big pile of ADA and Fortran made a table that 
made all the exposed film useful.


The proposal was to take one of my friends boards, and toss the two 
containers and replace it with a Sparcbook (or whatever on that scale 
Sun proposed).  The entire pile of software was guaranteed by another 
bidder to do the job of telling where the plane had been w/o the 
original stuff, and run completely on the Sparc system.  It was to be a 
laptop according to the guy we talked to.  The information would be 
available on the flight line, rather than some time later, making it 
perfect for such as NASA.


My understanding was that the format was classified, so we had also to 
guarantee it would work w/o ever seeing any data.


I told my buddy @ Fintec and the gentleman from Burbank, that I'd be 
glad to deliver all the boards he needed for a check ride :-)


Anyway they never ordered any product, and not that long after the 
absolute last hope of them ever flying was canceled.


Also, I was told that the orders had been made to gather all the 
containers of equipment I mentioned above somewhere at Edwards and 
destroy it.  The SR71 program was not canceled, it was destroyed with 
prejudice.  I think it had risen from the ashes so many times, and was 
such a suck on the budgets of the involved agencies, that they wanted to 
kill it with a stake thru its heart this time.  Very sad.


I've probably told this in the distant past, but it is something I'd 
have at least liked to turn into a visit to see one of the things while 
it was operational.  I also never saw one flying.


The closest I came to an aircraft in this class was an almost on a 
Concorde Ticket in the late 70's when an upgrade to first class could 
get you near to the Concorde fare, and then on a visit in the 90's I got 
to see one take off like a rocket @ Heathrow.


Would be curious if the ones here who do tape remember doing business 
with Fintec, or any of the guys who used to trade drives and repair 
services.  I knew a lot of them and supplied parts and help to them thru 
the 70's and 80's.

I once got held, waiting for a runway, probably London Heathrow but somehow 
Manchester sticks in my head. Any way there was a Concorde queued infront of 
use waiting for a Concorde to land.
So I go to watch a landing and a takeoff...

The BA Concordes at Heathrow lived in a hanger at the eastern end of  
the main runway.
The perimiter road intersected the main runway so the bit with the 
hanger was to the left and the main runway to the right.

No fences no gates.

The Concordes would be towed by the usual tug  to and from the terminal 
area to the hanger.
A guy in a little hut (moreof him later)would switch on a sign saying 
'Aircraft crossing - STOP'
Cars would stop and the Concorde would be towed across and the the sign 
would go off.
I had this happen loads of times as the DEC wharehouse was on the south 
side of the airport .


Well one fine day I drive down and on goes the light and  I stop and yes 
here comes the Concorde and across it goes

and out goes the sign and I start to move with the queue across the gap.

Then it hits me where is the tug? OMG its taxying on engines and is 
about a hundred yards up the  runway.
They wouldn't would they. Oh yes they did! Full throttle full 
afterburner and off down the runway.
The guy in his little hut passed me going east at about 30MPH and those 
of in

cars got about 7.9 on the Richter scale in shaking.
Piles of rust and dust were left behind when the cars moved off.

AlphaServers?

Does anyone here know why certain AlphaServers are worth such seemingly high 
prices on eBay still?

Particularly the DS15's seem to be worth their weight in gold, and the DS10's 
still sell for quite a bit.  I see DS25's and ES47/ES80's get listed all the 
time for fairly high prices, but never sell.  I'm just wondering why the 
difference.

Given that the Alphas have been end-of-life and kind of dead-end for a while 
now, I'd have thought some of the more recent ones would have fallen into the 
realm of hobbyist affordability by now.  Especially since I can buy a much

Re: Coating on older DEC slides

2015-06-19 Thread Noel Chiappa
Thanks to everyone for trying to help, but I'm not sure we've cracked it yet.
This coating is _not_ a lubricant: it's a hard, thin even coating over the
entire piece; it cannot be easily scraped off (e.g. with a fingernail), but
requires a knife tip or somesuch. So I think that rules out the molybdenum
disulfide suggestion.

A few comments to various replies:


> From: Rod Smallwood

> It might be cadmium

I don't think so; cad-plating produces a surface which is either silver, or
yellowish (cadmium dichromate). (The yellowish coating one often sees on
later DEC equipment is probably not cad, but zinc-dichromate; see here:

  http://429mustangcougarinfo.50megs.com/new_page_26.htm

for a good intro to distinguishing platings. This makes it sound like we
might be dealing with some sort of phosphate plating.)


> From: Mike Ross

> I do hope not; that stuff is *seriously* toxic.

Indeed: "Cadmium is very toxic and should not be used on any part intended
for use where direct food contact could occur"; but it is/was used to plate
things (especially in the aerospace industry, where it reduces the tendency
to galvanic corrosion when placed in contact with aluminium).


> From: Al Kossow

Did you mean molybdenum disulfide (which I don't think it can be, for the
reasons given above), or some other form?

Right, but I'm not just looking for _a_ coating, I would really prefer to use
_the_ coating that DEC did originally (if it's still available, of course).

Some off-brand slides are zinc; and, as I said, I think a lot of later DEC
stuff (racks and frames) is dichromate zinc.

Right, but this coating doesn't look like it was painted on. It's got a
finely textured surface that is rougher even than flat paint.

I am baby sitting three ES45s, two DS20s, and a DS15 all running Tru64 Unix
5.X.  Yes, you can buy a used Dell desktop at any garage sale that has more
memory and CPU than a DS20 but it doesn't run Alpha VMS or Tru64 apps and
that is not very helpful if your data centre has one or more Alpha
applications that are still in use.

The DS15 is the newest of the hardware you listed and only 2 or 3 rack units
high so it relatively compact and less power hungry than most of its older
brothers.  The DS20 is bigger but still can be put in a modest amount of
space and the lights don't dim when you turn it on.  The ES45 is a large box
(but smaller than my AS4100) able to accept four 2GHz CPUs and 32Gbyte of
RAM from the days when that was impressive - it is a big pig.

In my humble opinion, Tru64 Unix is a very good operating system and the
advanced file system is very reliable with clustering capability and a
distributed lock manager - they were attempting (successfully) to provide
the high uptime/clustering features of VMS on Unix.  If Linux keeps at it
for another ten years, they might almost catch up.

My employer is supposed to be migrating the apps off of the Alphas and onto
Linux by the end of 2015 but, by their past performance in such endeavers,
some of the Alphas could be running for another five years.  They pay about
$50,000.00 a year to HP for support so it would have been worth their while
to finish this migration years ago.

I will get my pick of them as they are shut off so I might put OpenVMS one
of them, maybe I will even use it to replace my AS4100 which was the box
that the ES45 replaced some 15 years ago.

I suspect in actual combat would be 1947 in Israel (as the S-199).
The aircraft used in the film were all Buchons, not "real" Bf-109s.
There are a surprising number (4+) of "new build" Bf-109G and K models. 
They're "technically" restorations because they're building around an 
existing data plate.  A leader in this is Arsenal 45.  They've already 
finished the build of a brand new Bf-109K4.  There are also a few people 
involved with building brand new DB-601 engines based on scanned parts, 
original engineering drawings and newly created drawings from existing 
parts.

Avro Canada CF-105 "Arrow"; look it up, and see why one of the first
things I plan to do if someone ever invents a time machine is go back
to 1959 and introduced my steel toe boots to Diefenbaker's crotch,
repeatedly.

Then again, that did give us the Gemini capsule, since I believe
McDonnell (among others) ended up snapping up the unemployed Avro
Canada workers. (Thanks Diefenbaker, you screwed our aviation industry
in exchange for some shitty missiles we didn't want, and a bunch of
early warning radar sites that were obsolete in minutes... oh and
they're all environmental disaster sites.)

I have two of the dual proc ES47 boxes and the cables to interconnect
them as a single quad proc system. I think 8GB of memory in each box.
The boxes themselves didn't cost too much, but the freight shipping on
a pallet wasn't cheap. They are heavy and long and awkward to set up
without a deep rack to put them in. I don't have a good space set
aside right now to properly and somewhat permanently set them up and I
have rarely powered them on. They are by far the fastest VMS system I
have but for hobby use have rarely been worth the bother.

Dow Chemical in Fort Saskatchewan, Alberta still has VAXen running some
version of VMS to control the process in their chemical plants.

About 15 years ago, a Compaq service technician told me that he had to
maintain a VAX-11/785 that controlled a Lockheed L1011 flight simulator in
Vancouver so there are probably still VAXen doing that job around the world.

I notice you're (probably) in the UK.

If you get no other offers, I can almost certainly find you a couple of reels. 
No idea what
is on them, I have a (single drive) TU56 [1] on my PDP8/e which came off 
another 8/e. Since the
tapes came with it, I would guess they're formatted for a PDP8 system, but I 
can't be sure. I have
never had the time to get it all working...

[1] No, not a TU55. This is a TU56 with just one transport and a blanking plate 
over the other holes, It is
an official DEC variant.

Where are you in the UK? I am wondering if I have to trust ParcelFarce with 
them...

OK, I went off and had a look at the page.  It does not say that the
older logo existed before 1957 (when DEC was founded), only that it
was earlier than the familiar design.  You simply read too much into
the "designed in 1957" part.

I suspect that the date is wrong in any case, because the "dec" logo is
obscurely visible on the #1103 System Building Block seen in the picture
on the Wikipedia page,[1] and first ship on those modules was 1958.

While I was at the bench working on another project I took a couple of minutes 
to breadboard the circuit (Q1-Q3), turns out it switches before the capacitor 
goes into reverse charge, so the cap does retain the proper polarisation 
throughout the charge/discharge operation cycle.

Experimented with separating R8/R9 into isolated emitter-bias and 
collector-load resistors, can still be made to oscillate but becomes more 
touchy, so I do suspect the particular oscillator design was chosen for 
stability, also considering a common flip-flop astable could have been in fewer 
components.

(Coincidentally, the other project was repairing one of those common flip-flop 
astables (master clock in a 1971 calculator) which was intermittent. 
Measurements ruled out the Rs as a problem, so narrowed it down to the two 
transistors and the two capacitors, at which point it became a question of 
shotgun replacing all 4 components versus trying to isolate it further. Tried 
individual hot / cold checking of the 4, the osc. rigorously stopped with heat 
applied to a 60pF ceramic cap and restarts after blowing it cool.)

DEC architecture machines were in the serious minority when it came to
military computers in combat service. DG/Rolm was huge, as was Univac.
IBM, Burroughs, and CDC had a slice of the market as well.

I don’t know that one.  But I do know that RC25 support in RSTS/E was driven by 
a large Navy order for PDP-11 systems running RSTS/E on RC25 drives, for use 
aboard ship.  Or more precisely, if I remember correctly, aboard submarines.  
I’m not sure whose; some vague memory say Royal Navy but that may not be

To tie these two lines of question together (and bring it back very much 
on-topic), the BINAC (amongst the first stored-program computers, 1949)
was supplied to Northrop for research into airborne flight control (quick web 
search says part of the Snark missile project),

I'm not suggesting the BINAC and YB-49 (the flying wing) were connected, but 
it's interesting they were contemporary projects both at Northrop, and computer 
control was just what the flying wing needed.

Another example of shipboard use:

Quote from  HP Measure Oct 1976:
One of the first 2116As sold is still being used aboard a research 
vessel operated
by Woods Hole Institute of Oceanography in Massachusetts, which has 
purchased
at least a dozen other HP computers since then. The original one still

"One of the first 2116As" would place this at 1966-1967.

When I worked at IBM Boca Raton, on one of the buildings was a ship based radar.
It was installed to do testing for the ship mounted System/3 that IBM sold at

Don't forget Cromemco:


From Wikipedia:

https://en.wikipedia.org/wiki/Cromemco

In 1981 a study was commissioned by the United 
States Air Force Systems Command to select a 
microcomputer for theTheater Air Control System 
(TACS). From a field of 149 microcomputers the 
Final Technical Report concluded that “the 
equipment offered by Cromemco is the most 
responsive to the general selection criteria.”[31] 
In the years following this study the United 
States Air Force became a major customer for 
Cromemco computers.[32] [33]


Cromemco developed a special version of the CS-200 
computer (called the CS-250) to meet the 
requirements of the Air Force's Mission Support 
System (MSS). The CS-250 had a removable hard disk 
based on patented Cromemco technology[34]The 
United States Air Force deployed 600 Cromemco 
Systems from 1985 to 1996 as Mission Support 
Systems for the F-15, F-16, and F-111 
aircraft.[35][36] These systems received their 
first war time use in Operation Desert Storm in 
1991.[37]

It turns out that was partly by design.  Recently I was reading an
interview with Ken Olsen that I hadn't seen before.  In it he was
saying that particularly in the early days DEC made a point of
avoiding government, especially military, contracts.  All of the
special accounting and record keeping that was required was
more trouble than it was worth.

The format is described in the manuals.  And while the PDP-11 formatter I have 
seen doesn’t do 12-bit format, it seems like it would be a simple programming 
exercise to convert it to produce that.   There’s nothing in the drive itself

Speaking of weird military applications of small computers, I still have a 
paper from the early 1980s about using Ethernet and a small PDP-11 to measure 
nuclear warhead yield.

The scheme goes like this: run the Ethernet coax cable down the hole at the 
bottom of which sits the warhead being tested. The PDP-11 is at the top of the 
hole.  At T=0, start sending back to back Ethernet frames.  Record the TDR 
value associated with the transmit error for each failed transmit, and send 
that to the data collection site which is some miles away.

The changing TDR value will tell you how fast the Ethernet cable is evaporating.

I’m fairly sure this was real, not a made up story.  I should dig up the paper, 
it’s just one page long.

The original poster wanted examples of minis "setup and used on one".
I doubt a Cromemco would survive long in flight service. This is why I
also pointed out "combat service", as opposed to being part of a test
set in an air and power conditioned hangar.

Military aircraft (and marine) service is *really* hard on equipment.

All,
My 14-year-old son has mentioned that he’d like a breadboard and some

VOM already, and I’m thinking about turning him loose in August with the

Horowitz and Hill. 
Is there a reason to prefer 7400 series over CD4000 series logic? 

http://www.jameco.com/Jameco/catalogs/c151/P30.pdf

makes the CD4000 series look cheaper. 

I also have a pair of old Tek 922 O-scopes, one of which has all of its 
knobs and switches intact and produces a trace. I’ll guess that they both need 
rebuilding; I have the instruction manuals, though, so maybe that is lesson 1? 
Is the TekScopes group the best place to find probes for one or both?

I also have one of the 200-in-1 spring-termial projects; he played with 
that a bit, but there wasn’t enough logic there to do much computing :-) so he 
lost some interest.

He has a Raspberry Pi, which he pretty much contempts in favor of his 
laptop, which will play the modern version of MineCraft :-P, but presumably 
hooking those together might be fun. 

Should I add anything else to his pile? Is there a series of logic 
that’ll make things easier if he does end up hooking in the RPi?

Thanks for any help! My own knowledge is pretty spotty in this field, 
so please feel free to start near ground-zero with helpful advice.

4000 series are really much more static sensitive than bullet proof ttl
there are pros and cons to everything 4000 series can use a higher VCC

An acquaintance just the other day showed me an Arduino experimenters kit that 
came with breadboard, LEDs, jumpers, etc, all in a compartmentalised plastic 
box for 28$CDN. Haven't used it myself, just saw it briefly. Maybe you want to 
start him out at a lower level of logic than that though, or alternatively 
maybe he can move from that to incorporating & interfacing lower levels of 
logic.

Something like this, but this is twice the price:

An annoyance of the Rpi for this stuff is the GPIO pins are 3.3V, they need V 
clamps on input from TTL at least. Not sure where the Arduino fits in that 
regard.

Let him play Minecraft. Start with simple redstone contraptions, then
move to command blocks.

I'm not ashamed to admit I (24 y/o) play Minecraft now and again (with
friends on their own private servers). I'd suggest anyone serious
about trying to get someone "into" logic and programming with
Minecraft use a good tech modpack like the Direwolf20 modpack (part of
the Feed the Beast launcher). It has Immibis' RedLogic, which is
redstone wiring and logic gates; as well as dan200's ComputerCraft
which gives you a Lua programmable computer (and peripherals) that can
do all sorts of neat things.

Eloraam's RedPower 2 had a *very* nice 6502 system (yes, really) that
ran FORTH (though you could have your own asm in game as well, but
you'd need to find a way to import it); it also is the "original"
redstone wires and logic gates mod. But it stopped being worked on
back in 2012. Which is really too bad as the 6502 with Forth was very
neat (it was also graphically styled after a PDP-8/e).


Anyway, sorry for the Minecraft "crap" if anyone here doesn't like it,
just wanted to pitch in my two cents.


Cheers,
Christian

I have a National Geographic somewhere on my shelf that has an article
about remote sensing and I vividly recall at least one interior shot of the
U.S. government aircraft used to gather the imagery for the article; it was
fitted with a bunch of operator workstations for the folks operating the
various sensor platforms and I could swear the stations were built around
something in a BA23 ... probably a VAX given the vintage of the article ...
I'll have to see if I can find the picture real quick & I'll try to scan it
up.

Here's the picture if anyone's interested; it turns out that the issue is
from 1993:

http://wildflower.diablonet.net/~scaron/aerialBA23.jpg

This may have actually been a University operated project; I don't believe
it's actually a military aircraft ... but I see at least one BA23 in the
cabin :O I believe the aircraft is a DC-8.

Sorry, had to be said.

Minecraft has nothing to do with logic or electronics and would just be 
an unnecessarily obtuse way of approaching it.


For an adult with too much time on their hands? Sure...

I'm not ashamed to admit I (24 y/o) play Minecraft now and again (with
friends on their own private servers).
When I visited ALR, a company in Irvine that evolved into making PC type 
servers and were absorbed into Gateway (name still is used) had a lab 
with a lot of hardware stations, and for the time good networking.  At 
about noon or so one one of my visits for Sun Microsystems, about a 
dozen of the engineers showed up and proceeded to pull out hardware and 
cables, and displays at various stations and hooked them all up pretty 
quickly.  This was in about 92 or 93, I'd guess.


They converted the lab into a big Doom game for about an hour.

I also found out the best time to round up and have casual consultations 
with them about things I wondered about with some systems.


Thanks
