I've got a bunch of Nuclear Data peripheral circuit boards that I need
to reverse engineer. They are simple circuit boards with all the
tracings visible (i.e. no internal layers) and the parts are all 7400
series logic in standard DIP packaging.
If I were to do this manually, I would take high resolution
photographs of both sides of the board. From the photographs, I would
try to recreate engineering drawings: part placement and circuit
topology.
I'm wondering what kind of tools are out there that would assist in
this. Could I process the photos to extract the topology of the
printed circuit traces? Can I correlate this with image recognition
of the part packages and combine them to product a netlist?
I'd appreciate hearing any experiences from others that have reverse
engineered circuitry.

I make the bulk of my living converting documents in WordPerfect 5 and
up, IBM DCF and Bookmaster, and Interleaf to current formats.
Is anyone interested in hearing a bit about the problems using current
word processors to import the old formats? It's sort of on-topic, as
these are vintage products, even if still in use, but I won't bother
the list if it's not of interest.

I'm going to plunge into the world of slightly more advanced
electronics, and one of my teaching tools is a Velleman PCS64i that I
just inherited. It's an o-scope front end that interfaces to a PC to
provide the display.
I'm looking for the DOS software - it is not available on Velleman's web
site any more. I found the Windows software, but I'd rather keep it
simple for now. If you have the DOS software please let me know ..
Thanks,
Mike
The setups I have seen require a lot of square footage. You have printers, tape drives, and big DASD farms connecting to controllers and communications controllers and finally the mainframe which may itself be a complex consisting of more than one physical box.
I have not seen a machine room that wasn't all raised floor. I don't know that a small setup exists with the bus and tag technology but that was years ago. The new stuff is smaller and also doesn't need raised floor. Seems like it's probably an either or situation. When you need raised floor you need a lot. When you don't, you don't.

The other problem with raised flooring is who's floor are you on?
With a small system, could a raised island be built, with the computing
equipment raised say a foot or so, with just false floor between the
equipment.

Interesting article about the 40th anniversary of
the progenitor of many modern operating systems.
It even mentions our very own Al Kossow,
"One holy grail that eluded us for a long time
was the first edition of Unix in any form,
electronic or otherwise. Then, in 2006, Al Kossow
>from the
<http://www.computerhistory.org/>Computer History
Museum, in Mountain View, Calif., unearthed a
printed study of Unix dated 1972, which not only
covered the internal workings of Unix but also
included a complete assembly listing of the
kernel, the main component of this operating
system. This was an amazing find?like discovering
an old Ford Model T collecting dust in a corner
of a barn. But we didn't just want to admire the
chrome work from afar. We wanted to see the thing run again."

As I mnentioend the other night, I've added the parallel printer port to
that TD1100 viewdata terminal. The output is a DA15 socket, and in fact
the hardest part of adding the port was cutting the back panel of the
unit ot allow the conenctor to come through. I had to remove the back
panel entirely from the PCB, which invovled desoldering the line wires
and the mains wiring....
Anyway. I then had to make a cable from the DA15 to a 36 pin Microribbon
conenctor to conenct ot a Cnetronics-interfaced printer. As I mentioend,
I'd gueessed as to what the signals were, so I sued those guesses for the
initial wiring.
Connected the unit to an old Epson FX80+ and pressed the 'print' key on
the terminal. It printed. Some garbage, some readable text. I then
rememebred the pritner setup screen (type 'P#' at the dialer screen) and
found it was set to 'teletext compatible' -- i.e. it would handle the
various teletxt/viewdata controll codes and graphics. I reset it to
'ASCII text' and tried again. This time it printed correctly -- almsot.
It was double-spacign the lines.
I then realsied that the pritner had previously been used with a BBC
micro, a machine that, by default, sends only a <CR> as a newline.
There's a DIP swithc in most old Epsons to cater for this, it foces the
AutoFeedXT line on the inteface conenctor low. Only problem was, I didn't
haev the printer manaul.
Oh well, I just took it apart and traced the conenctions from the
AutoFeedXT pin through the filter resistor to a DRIP swithc. Turnrf it
off (so it no longer asserted the AutoFeedXT signal) and put the pritner
together. This time it worked fine. My gueses on the printer port signals
had probed to be correct.
In case anyoen else wants to do it, here's the wirelist (and colours) of
the cable I made :
1 o----D3------Or----o 5
2 o----D6------Bu----o 8
3 o----D7------Pu----o 9
4 o----D0------Bk----o 2

Hi guys,
Does anyone here have a surplus of GPIB, HPIB or IEEE488 cables (they're
all the same thing) with metric threads? (the thumbscrews will probably
be black -- the silver ones are AIUI usually some SAE thread type or other).
I'm after a couple of the short 1-2ft "instrument to instrument" cables,
a 1-metre (to replace a nasty little knockoff cable which has
excessively long thumbscrews) and a 2-metre (to replace a buggered up
Belden cable).
These seem to be commanding utterly insane prices on Greed-Bay, and are
basically unavailable elsewhere...
Thanks,

Legalize Adulthood! <http://legalizeadulthood.wordpress.com>
I've got a small Viewdate (PRestel) terminal on the bench at the momnet, a
Tandata TD1100.
I've made a few modifications, in particular I've removed the RF
modualtor (which I find to be a pain), added the RGB oupt ucomponents,
and fitted a 3 pin DIN socket in place of the redundant RF output socket
with the pins wired to the audio signal, compostie video and ground. So I
can now use it with compoite or RGB monitors. I've also added the printer
port components.
[For reference, the RGB output components are the ones hidden by the
modulator can. The IC is a 74LS364, there are 4 resistors, all 220 Ohm, 5
picofuses to protect the telephone line agians a breakdown i nthe monitor
wihci puts a high voltage on the input pins, 8 5.6V zener diodes and the
5 pin DIN socket. Fit the link F-D to get TTL sync.
For the compopstie output, fit 10uF or 47uF capacitors in the 2 spaces
hiddle by the modulator. Reduse the seires reissotr in the compostie
signal (I think it's R9 on the PCB) from 1k to 220 Ohms. Fit a DIN socket
in place of the RF output socket (the fibreglass insualtor of the latter
can be drileld ot take a single-hole mountign DIN socket) and wire the
pins to ground, the right hand hole of R5 (audio) and hole E (video).
For the pritner prot, the 3 missign chips are 74LS374, a 74LS365 and a
74LS74. Since these have different numebrs of pins, it's obvious which
goes where. The outptu conenctor is a DA15, you have yo cut a regtasnlge
out of the back panel.]
anyway, it does seem to work. I've conencted it to another modem[1] --
neither needs any DC line 'battery' so just connecting them together was
enough. I've discovered that from the 'dialer' screen, presing '#'
energises the line relay and conencts the lien audio to the audio output.
If it then detecs a carrier from the remote modem, it goes into on-line
mode, it then disables audio fro mthe line to the audio output and turns
on tis transmit carrier. Obviosuly trasmit ias at 75 buard, receive is at
1200 baud, it's 7 bits, even parity (and it cares about the parity).
[1] An old Miracle WS2000, the black box with 3 knovbs on the front that
weas commonly used with the BBC micor. It's an AM7910 and not much else,
I like it because it can be controlled from the front paenl rotary
swiches, and I Know exactly waht it's going to do. Since I only use it on
a private system (my line simulator), I've eneabled the Bell modes by
remove the pin from the rotary switch. I'd love to find the autodial and
answer boards for it, but no chance...
So far, so good. But one thing I can''t figure out on this TD1100 is the
dialer. The dialer scrren shows 6 telehone numbers which I beleive are
stored in battery-backed RAM inside the unit. at this screen, typing in
1 to 6 followed by a '#' dials that number foem the list and then goes
itn othe on-line mode. As I said, a plain '# gopes into that mode iwthout
dialing. Most other keys give a 'Please Try Again' error message. A 'P'
(must be upper case, and note that caps lock is cleaered whenever you get
to this screen) goes ota printer setup page (3 options). What I can't do
is figure out hoe to set the numbers and/or dial an arbitrary number
entered from the keyboard (ad since the battery in my unit is long dead
and I've removed it, all the numbers on the lsit are strigns of zeros,
not that useful!). I really don't want ot have to disassemble the firmware.
Another thing that would be useful, but I probably can figure this out,
is the ppinout of the DA15 pritnr conenctor. It's clearly TTL level
parallel. There are 2 opuptu ports, oen 8 bits (data I assume), one 2
bits (I guess one of thsoe is strobe, what the other is I don't know) and
3 inputs (one is conencted to a pusle-stretcher, adn is prsumably Ack/,
one of the others is probably Busy).
Any ideas?

I've been more seriously contemplating my QBUS multi-purpose card idea now that one of my other major projects is nearly done. I've been unable to find any official or even quasi-official mechanical specs for DEC cards (QBUS, UNIBUS, etc). I'm obviously looking in the wrong places, since there's a wide degree of uniformity; I'm looking for things like board outlines, edge bevels, component clearances and the like. The electrical specs are in quite a few places, so I'm not worried about that.
Interestingly enough, my Douglas CAD software for my old Mac has DEC card outline templates pre-stored. However, I'm not even entirely sure Douglas makes PCBs anymore, and I imagine they can't beat my preferred board house on price (I'd love to be wrong).

Hi
If you live close to Gothenburg and can act within a few days I know of
some medium sized alpha and small vax machines available for pickup.
VT100 and VT520 terminals also.
Contact me offlist.
Regards,
Pontus.
There's a Wyse WY-50 terminal which has been sitting in a box in a
warehouse for nobody-really-knows-how-long which has recently come into
my hands. I haven't tried powering it up - it probably wants a good
checking-out first - but it looks to be in very good cosmetic condition,
and the people who gave it to me say it was working when it was stowed.
Keyboard, power cord and manual are all with it.
It's in Seattle.
Free if you can pick it up (Seattle Center, Opera House, we can arrange a
time), or UPS shipping costs if you want it shipped. Slight preference to
anyone who's willing to pick it up. :) E-mail ohh at panix.com if
interested.

Looking through some pictures my sister in law had brought over.? Everyone was ooing and ahhing about the cute kids, except me.? I noticed in the background of one my old DEC PDT 11/150 and a VT100.? Circa 1982 those were the latest and with a modem allowed me to log in to the VAX at work.? Good stuff!? Also a Heathkit H19 terminal that I had built from a kit.
The PDT 11/150 was an LSI-11 single board computer stacked on top of 2 8in floppies.? That thing really clattered when I ran it.? I had bought a UCSD P-system for it from a UCSD spin off that supported that box.? The PASCAL was compatible with the Apple II so it was actually useful.? I wrote a 2D gravity modeling program for it that my boss ran on his Apple II to his hearts content without any mainframe charges.??
I can even remember how much it all cost.? The PASCAL system was $500, the H19 $500.? The VT100 and modem were loaners from work, the PDT 11 was free, DEC was giving them away to good customers, I suppose because they couldn't sell them.? Good times.

Does Hay-on-Wye, (Y Gelli Gandryll), the famous Wales book town, have
a shop dedicated to tech or classic computing?
I've had dinner with King Richard Booth once or twice. He had the
idea to buy up all those shipping containers of old books otherwise
destined for the pulper, and sorting them by topic and creating
used book shops throughout that city.
I have a similar pile of old Mac Think C era books and Mac developer
program newsletters. And then there's all the MSDN CDs and C compiler
stuffs from various PC compilers. Not quite sure what to do with it all.

Hi Jim! Thanks! Although the SCSI to IDE/SD project is going slowly I did get about 20 PCBs earlier this year. So far we've gotten some builds underway and at least one builder has gotten the board to run Zapple as a debug monitor as a "proof of life".
The project is quite a ways and is nearly complete. All it needs is some community involvement to push it to completion. In particular, it needs verification of the IDE, SD, and SCSI interfaces. Then it will need some firmware to handle the conversion.
The main advantage of the project is that it is completely open and free. If there is sufficient interest, I will order another batch of PCBs or try to get those builders with incomplete PCBs to swap them out.
In my opinion, this project is nearly complete and the shortest path to a working SCSI to IDE/SD converter. All it needs is some TLC and push from the community. As per the usual N8VEM guidelines this board uses all commonly available parts and is designed to be simple to assemble using basic tools.
Please help finish this project. I sincerely think it will be valuable for years to come and it would be nice to discuss an actual converter during this frequent topic on CCTALK.
Thanks and have a nice day!

PS, I recognise the microcontroller/FPGA/CPLD approach is valid but they never seem to get off the drawing board.

I want to play with a russian K1801BM2 CPU (K1801VM2).
My russian from the school is very very rusty and so I have problems to
understand what's going on with this CPU while startup.
There is some "besadresnoe tschtanie", a read from the bus w/o
sending out an address before w/o active SYNC.
It is right, that this read is building the upper 8 bits from the start
address in the rom area with Systemu Mode (Halt Mode) = 1?
Can anyone please confirm this?
BTW: how is this external register to be done in HW?
Does anyone know if there are schematics of SBCs existing w/o special
support ICs like The K1801VP1-55 or so?
Kind Regards and thanks in advance,
Holm

>Here's something I was thinking about the other day. I *know* for a fact that SCSI interface hard drives existed with 8" platters. I've never seen one, however. Does anyone know of any specific model numbers, or have any product information or pictures of such devices?
I just looked in my collection of 8" drives. I have two 8"
Imprimis/CDC 97201-12G PA8P1A ST81236N Sabre drives with the original
style SCSI connectors on the back. There are manuals for the drive on
Bitsavers at: http://www.bitsavers.org/pdf/cdc/discs/sabre/83325700N_PA8xx_736-1230mb_Par…,
and http://www.bitsavers.org/pdf/cdc/discs/sabre/83325720F_PA8xx_736-1230mb_Mai….
The manuals say that the drives are 1.2G, 512 byte/sector drives with
an HP SCSI differential interface. I can post pictures if you are
interested.

I know I kind of touched on this in my earlier diagnostic query, but I
thought I'd send out a more obvious request:
Anyone have a memory expansion for a Vaxstation 3100 (model 30) they're
willing to part with? Something 8MB or larger would be wonderful. I
have a wide variety of DEC (and other) hardware to trade.
Thanks as always,
Josh
I have received a few requests for the Donner 3500 instruction manual,
which I have posted on my site, with related docs
http://vintagecomputer.net/browse_thread_record.cfm?id=421&tid=9
It appears a few of these are popping out of the woodwork lately. There
are now at least 8 now known to exist, maybe more.

Tonight I finished reading Walter Isaacson's book about Jobs. It is very good, and I highly recommend it.
I urge cctalk'ers to read it and constantly keep in mind * the big picture * instead of being your usual nit-picky selves about tech details.
Hey everyone!
I need to raise some money for gifts this year so I'm cleaning out some of
the systems I don't play with any more.

12" color monitor. Owner's reference and getting started guide.
* 22 8" floppies ($10, will ship)
If they weren't so big they'd make great stocking stuffers. Maybe they can
be hung outside the stocking?
I suspect many of use have this sort of problem, and I'd be interested in
hearing any solutions to it.
Moat classic computers have various little bits that go with them, in
particular cables and connector adaptors. In some cases these are
specific to one particular type of machine (e.g. the user prot adaptor
for the Acor Cabridge Workstation), others are rather more generic (the
same cassette lead fits all TRS-80 M1, M3, M4 and M100 machins, along
with the IBM 5150), and still others are totally generic (HPIB cables,
'kettle leads', etc).
I find storing thes parts, partircularly the 'somewhat generic' ones is a
problem, and I can never find what I need. You cna't categorise them by
machine (becase, for example, a TRS-80 M1 RS232 cable is specific to that
machine (it plugs into an esdge conenctor on the EI), the pritner cable
also fits the M3 and M4 machines, the cassette lead also fits the IBM
PC), you vcan;'t realy do it by function (a DBd25-DB25 lead could be used
for several purposes, not only RS232), and so on.
Any ideas? I am getting fed up with having to re-make a cable which I know I
made a couple years earlier, but for a different machine, and which I now
can't find.

I believe they have multiple (6? More?) Pentium or Pentium Pro processors.

I might be soon coming into possession of some
Data General stuff. Maybe an Aviion 66. There's
a second one, maybe a model 37? I'm not sure. No
drives. I'm going to see what's there and post
the inventory in the next few weeks. I've never
heard of any demand for these; anyone know if
there would be any interest? I realize my
question is based on pretty sketchy information so far, but that's all I know.

As a follow up to Richard's question, does anyone have any experience
archiving an Xebec S1410 / S1410A SASI controlled drive from a
relatively modern system? If the SASI controller doesn't support the
standard SCSI Inquiry and Read Capacity commands I wouldn't expect
that you could simply connect it to a SCSI host controller on a Linux
box and "dd" the drive contents to a disk image file.
