There's a copy of the IEEE Std 696 in my lap. I've been searching for this document in "the pile" for quite some time and it's held up my work on a bus probe for the S-100. I intend to run the S-100 from my PC and have completed circuitry to enable transfer of data from the PC to the probe at a maximum of about 2 MHz. Now, this is entirely fast enough to run the bus, with the exception that it probably can't run it continuously at that rate, hence I've contemplated inserting a state machine to operate the bus automatically in a series of operations while sampling the activity on the bus at the same resolution as that at which it is being driven, e.g. 8 MHz for a 2 MHz processor clock, and more or less at that same proportion otherwise.
Unfortunately, I'm not convinced that it's necessary for me to have a really long sample memory (has adverse effects on price and circuit complexity). What's more, though I've considered including a large crosspoint switch for both writing and reading signals from the S-100, at real time, I'm not sure it will be of sufficient value to the user public. Its purpose is to allow compaction of the data transfers during a simulated bus transaction in real time. What's more, in order to get 2 MHz throughput, even in bursts, it requires I operate the device at around 100 MHz internally, which will be both costly and difficult.
Originally I intended this thing strictly as a diagnostic tool. When I noted that IMSAI is bringing back its front panel board and the box to accomodate it, I figured it might be useful to provide a fairly automated method for testing and debugging the thing, including tests for shorts, crosstalk, I figured that the notion of putting a Pentium-class machine in an IMSAI box might not satisfy everyone's debugging an testing needs, particularly if they wanted to run REAL '70's era hardware.
My intention is to allow the PC to function as the front-panel, and, to small extent, as a combined pattern generator/logic analyzer, for numerous purposes ranging from backplane troubleshooting to peripheral testing. The plan is to provide functional support for things like block transfers, I/O-to-memory and memory-to-I/O as well as memory-to memory-transfers. Memory testing, at least superficially will be supported as well. I'm contemplating a graphical interface for purposes of stimulating the bus, though, again, I've yet to see whether that's useful enough to warrant the effort.
This is YOUR big chance to have input into the design of this device, assuming you have some idea of how YOU'd use it. I've got to break the functional sections up enough that the device can be sold as a "kit" not requiring FCC approval, so much of the cost will be in things like adapter sockets for the FPGA's and CPLD's, which often outcost the IC's by 10x. Since FCC approval will goose up the cost by 100x, I'm trying to avoid that.
If you're an S-100 user, particularly if you have experience in bringing up a system from totally dead to totally alive, I'd certainly like to see what your impression of your needs from such a device might be.

It's a cheap knockoff of the Apple ][ style, down to the wedge-shaped
cable cutouts on the back. They did change the lid a little. It doesn't
have the same fastener as an original, nor does the bottom slope up in the
front. Other than that... they are vey similar.

I know it sounds strange but I have a tape that I received with the 85 labeled
"HP200 Series 9800" made by Hewlett Packard. It is identical to the other
98200A tapes I have. I will post a scan of the label if anyone's interested.

I am looking for a source of new, or nearly new, HP 85 tapes.
These are HP no. 98200A, and are sometimes referred to as
HP200 9800 series. Any help would be appreciated. Thanks.
These are large phototypesetting machines of the first or second generation.
Autologic designed most of their own boards but sometimes OEMed CPUs. It
would be wise to check the CPU cabinet. Also check to see if the paper tape
reader is a punch also.
If it is working it could be a museum piece. I bet there are few left.

Ok, is there some trick to identifing pdp8/a quad height boards? Or maybe
most of these boards are not standard DEC issue... I have a lot of boards
that have wierd markings on the green or grey handles, all have VG DS on
two sets of handles, but one of those is covered with a round sticker with
a 3 digit number on it... very strange...

Greetings,
Does anyone here know anything about an Autologic APS5-1 system, model
number APS-5y-70-NFPA Type2? It's a rather large machine with a paper
tape punch, a large optical assembly inside the cabinet, a CPU with
lights and switches, and a serarate cabinet with a tape drive.
Between the 74xx series logic and the appearance of the system, I'm
guessing it was made in the 1970's.

Hi,
I visited A1 Vente Ordinateur in St. Laurent, Quebec, today. They're
still operating, and they've still got stacks of stuff.
Most of what I saw were monitors, and everything I had on my personal
list was 'out of stock' thanks to their recent problems, but they're
expecting more loads of stuff in the coming week. I didn't ask about a
MicroVAX because I was there by foot (quite a long walk from the Metro!)
and probably wouldn't have been able to afford one anyway. :)
Most of the stacks are off-limits to customers, but I did find a
NeXTStation in the public area. I didn't take it because I don't think
it can do anything on its own. :) I asked if they had a Cube, but they
didn't. No Amiga stuff, either, although they did have a Toaster 4000 a
while back that apparently sold very quickly.
Anyway, SPAMmers or not, I'll probably be doing business with them in
the future. There is, after all, a lot of stuff that never appears at
the Salvation Army stores. :)

One of the other recycled computer places I went to yesterday had an
interesting non-classic PC. It was a small, heavy, metal thing, with a
marbled paintjob, called a "Moby Brick". 486-DX25. It had a matching
marbled keyboard. Really cute. I would have taken it home with me had
it not been missing the external power supply, or if they hadn't wanted
$40 for it. (For a cute doorstop, maybe I'd pay $25-$30, but not $40.
At least not until I regret leaving it behind and go back for it. :) )
Anyway, I think this machine might be a future collectable. There are
so few modern machines with anything interesting about them, that I
think that unusual case designs might be the only thing to look forward
to.
Other than the BeBox and wierd Atari ST and Amiga clones, anyway. :)

I have heard from the folks at the Computer History Museum,

They have asked me to limit the number of pictures to five or less,

Thus shall I do.
The pix all came out well. I'll scan the ones I think are best and
we can find a classic computer site to put them on... I am trying

Has anyone out there heard of a Multi-Mac Apple ][ Clone, model MT-600? I
was digging along the back shelf in my basement and found one... it's been
there for quite some time (a friend abandoned it with me when I was still in
college).
It appears to be an unremarkable clone, c. mid-1983 (S/N 8306055, suggesting
to me a manufacturing date of June, 1983, which jibes with the chip dates).
Inside were two cards - a clone language card with a 4-pos DIP switch and
a clone dual disk card with PROMs labelled P5 and P6 (like a real Apple
Disk ][ card). The RAM is 8 4164s, the ROMs are a wad of 2732s. It booted
almost everything I threw at it except a "Castle Wolfenstein" disk that may
or may not be defective (I/O error on boot after loading the HELLO program).
I only bring it up because I have never seen nor heard of another one. The
usual Apple clones I'm familiar with are Lasers and Franklins. This is clearly
neither.
It was fun booting my box of Apple disks to see what came up. I threw at it
some unpublished software from a former employer - "Cross Swords", a game from
1983-1984 that pitted warriors in a fantasy setting against each other with
pre-programmed goals in a capture-the-flag scenario. It was mostly done when
the company folded following Reader's Digest abandoning the home software
market (they sold all of our titles, "Micro Mother Goose", "Alphabet Beasts
and Company" and "Micro Habitats", among others). I was most the C-64 guy
there, but I did Apple and BBC Acorn programming, too. We were almost
exclusively a 6502 shop. IBM games came at the end, but with CGA graphics,
our stuff looked better on the C-64 or Apple ][.

As you may have discovered, the M8192 is a KDJ11-AA, ie an 11/73 processor.
If it has -YB marked on it, it's an -AB version, which can accept an FPU,
and if it has -YC, it should already have an FPU. M8192's were commonly
sold as OEM boards, or as upgrades for 11/23 systems.
M7546 is a TKQ50, ie the controller for a TK50 'CompacTape' cartridge
drive.
Sorry, I can't help with the CTBC card.
I assume it has some memory and an SLU? And a card with a boot ROM?

Please make sure NOT to post any pictures taken on the Computer Museum

there at all. The museum retains the rights to all posted photos of
their facilities. If those get posted they may not let us take pictures

Hi, folks,
First, the important stuff. I was over at HSC Electronics (one of the Bay
Area's surplus places) last Friday (just before VCF), and I found that they
had carted out a whole bin full of Vector extender cards and prototype
boards, all marked at 75% off original price.
More specifically, their assortment of extenders included ones for
S-100, Apple II, MicroChannel (PS/2), and other vintage gear. I was quoted
$40 for a MicroChannel extender in decent shape, and I really doubt the
others would be any more expensive.
The store's web site, containing their address, hours, and contact info,
is at http://www.halted.com/
-=-=-=- <break> -=-=-
Now, with that out of the way... VCF was fun this year! There are only
three things that I thought could have been done better.
1). If a person had pre-registered for both days, mark as much on the
badge/tag/whatever. Don't require that they stand in line to re-register
the following day.
2). Real badge holders/badges for all concerned would have been nice.
Perhaps make those of the exhibitors and attendees different colors so the
ushers can tell at a glance who's going to be going where.
3). POST THE OPERATING HOURS on the signs next to the registration table.
I had completely forgotten what time the whole thing was supposed to start
and end, and I had practically no access to the 'net during my trip to
check the VCF web site.
Other than that, I enjoyed it, though I had other business to tend to, and
as a result was only there for a chunk of Saturday. I'd like to hear how
the tour of the computer museum went.
I'll see the lot of you next year, hopefully.

boards, so they're probably unusable. This list does not
include whatever is in the PDP8/e chassis, which I will pick
up tomorrow.
Of the 4 hard drives, the middle 2 said rl02 i think. The top and
bottom units didnt say what they were, and the hard drive I grabbed
was one of the unlabeled ones. Choosen because it didnt have
broken off connectors on the back, ie, it was intact. Others either
had broken connectors or power cord cut off, or both. Butchers!!!

This particular case might be just a bit more involved, since pin numbers
are more difficult for the unititiated to track between the 44-pin PLCC and
the 40-pin DIP. However, it really doesn't require one be a rocket
scientist to figure it out. Like many other tasks it requires attention to
detail. The original inquiry came from someone wishing, probably more than
anything else, to read the contents of his EPROMs without risking damaging
them. It's really not likely that will happen so long as power and ground
are connected to the right pins. An additional risk might be that data
outputs might be shorted to one or another of the rails. If one is careful
enough to avoid those bugaboos, reading the things will be no problem.
In fact, I'd recommend one attempt to do this via the EPP port.
BTW . . . If your printer port is situated at the usual 0x378, then an
outputb to 0x37B will generate a write to the data port (same pins as at
0x378) acocmpanied by an "address strobe" as part of the EPP standard
interlocked hardware-handshake. An outportB to 0x37C will generate a "data
strobe" in the same manner, requiring of course, that one interpret these
correctly and respond with the appropriate "wait" pulse on what would
otherwise be the "busy" pin. I'm not "up" on the Pentium instruciton set to
such extent that I can guarantee that if one writes a WORD to the
odd-addressed 0x37B location it will write the bytes to the two sequentially
adjacent locations, but I would anticipate that if one writes a long word
(32-bits) to 0x37C, most EPP hardware will transfer the bytes low==>high in
order, via the data pins, and acocmpany each byte with a data handshake.
That would certainly make it easy to read from a PLCC socket.

Just a quick message to those of us on The List who I met at
VCF... I had a FunTime, thanks to the FunTime everyone else seemed
to be having... even though I was conned into bidding on a Teletype
ASR35 and of course, it came home with me, like I have room for
another...
O well. ;}
A huge "THANKS" to Sellam and the Crew, and everyone who worked so
hard to make it all cool.
The other major cool thing was getting to put a associate a face
with the ASCII byte streams, at last.
The other other Major Cool thing for me, was the Computer History
Museum, wherein I (stern warning signs notwithstanding) actually got
to touch part of the Real ENIAC... I flipped one of it's old
switches.. hehehe... not to mention the two rolls of film I shot
there.
Here's to VCF2K! See you all there....
Cheers

Well... I found out that the PDP8 stuff was scheduled to be shipped away
tomorrow morning. They're only open to the public from 11am - 3pm T, W, TH.
So, I went out there.. Luckly I had send that email yesterday, as the guy
assumed my interest in the computer was a departmental request, which
overrides private interests.. And someone else beat me to the machines!
So, lucky me, the machines were held for me.
Anyways... The machines were in bad shape. Yes, it was a PDP8/e, and
yes there were 2 pdp8/a machines.. But someone had gone crazy with a
wire cutters, and all cables were gone or cut (the pdp8/e has a cut
power cord).
I managed to get the pdp8/e and one of the hard drives set aside, and
i did look in the pdp8/e and someone had taken the core memory stuff,
but there were still 3/4 of the card slots full of cards, so i can hope
this will be useful. At least 2 of the front panel switches are broken,
one missing.
Someone had already trashed the front panel of one of the pdp8/a units,
so i grabbed all the cards. then, I popped the lower part off the other
pdp8/a and grabbed all the cards I could, leaving only the few Hex height
cards behind the programmers console. So, I have some spare cards now...
One backpack full of pdp8/a cards, to be exact...
I also obtained a small RS-232 to current loop converter (without the
12Vdc 20ma power supply). And the top rack plate which is for a PDP8/m
which is in good shape except for a couple stickers that are on it.
All in all, I did what I could. One of my co-workers said he has a pickup,
and will drive me out there tomorrow to get those 2 boxes (pdp8/e and HD).
I expect the racks will be long gone before I get there, so what I have
is what I have.
-Lawrence LeMay
lemay(a)cs.umn.edu
PS: and no, i dont know what I have from the list of cards yet, though I
know i have the 3 main cpu boards at the very least...
I offered the guy $200, because the core memory was gone, and he said it
was way too much, so I asked what he wanted, and he says $30. I reluctantly
agreed...
I just wanted to say it was nice meeting the few of you I got the chance
to in my sprint through VCF this year. I was up on a combo
business/vacation trip (read: company pays for vacation if I do a little
work there) and had the whole family tagging along...those of you I didn't
get to meet might remember the guy with the shaved head brave enough to
bring 3 small kids with him...
As far as a SoCal version of VCF/swap...I'd probably actually get to stay
for more than an hour there, maybe even share my little piece of classic
computer heaven on en exhibit table! Sign me up!
Cheers,
Aaron
Mark game me this board because he didn't know what it was, and he wasn't
interested in it. If it is what I think it is, it's probably pretty rare.
It has 4 large Xlinx chips on it, a smaller Xlinx chip, a MC68020, and a lot
of glue logic. It's made by Micro Technology, Inc, copyrighted 1990, and the
sticker reads "CIQBA +". The only connector coming off the board is a small
10-pin connector like the one on a DLV11J. It looks like it's a Q-Bus
CI (Computer Interconnect) board, Is this right? Anyone have more info
on this? Web search turned up nothing useful...

I took many pictures at VCF, and many pictures while at the
Computer Museum. I will be happy to scan them into jpegs, if
someone has a good place to store the resulting files. My own
website is a little iffy right now as regards anonymous FTP.
I imagine there will be around 20-25 pix worth looking at.... I
will see how the Computer Museum shots turned out today... I took
them in available light.
Oh yes... I'd like to see a show of hands of those interested in
a SoCal VCF/Swapmeet... it was a lot of fun and I'm pretty sure I
will try and have one here early next year.

The SoCal VCF idea is a good one. Let's do it.

I would be *very* interested in a VCF East. I think that DC would be a fine
location as would Boston (but DC is more centrally located).

Oh, I agree with you there. Things get even worse when you go to the
11/73 family - there at least three dozen different boards
all based on the same J11 chipset that's in the 11/73. And some of those
boards are identified by DEC as 11/73's if used with non-PMI memory, and
are identified by DEC as 11/83's if used with PMI memory! And within
a given board etch, there are different designations depending on
the rev level of the J11 chip installed and the frequency of the crystal
that's installed.

I hate to admit it, but i use Outlook Express 4 and 5. I like it. It gives
you a choice of sending to groups or individuals on both email lists and
newsgroups. But if you are like me, you will always hit the wrong button
anyway.
OE 4-5 is free at the IE5 site on MicroSoft. If you have Win98, hit
start-Windows Update and you are there. OE 5 can also check you Hotmail
accounts for you.

I'm very interested in VCF Europe - could you put me in touch (privately) with
those concerned, please. (I've a good idea who it might be!). I want to help
make this happen!

Hi Henk,
it is worse: I have been at that place already two times,
once about two years ago, and then last Saturday --- these
people are _VERY_ effective at obtaining things, quite a few
people whom I asked about old hardware told me
"Eugenoe got it all already", referring to Eugene Miya, one of the
volunteers working for that organization. He is at NASA Ames,
deeply involved with many of the Supercomputer (and previous CDC)
sites here.
I tried the two email addresses of Mr. Bartsch at Synstar, both return
"user unknown". When I am back to Germany in two weeks I will
use the ancient technology of the telephone.
Thanks and regards
John
