Does anyone know what this is? It's on a board with six 74LS181's and
two 74F582, as well as some static RAM and a ton of other TTL logic.

I spotted two of these in a scrap place yesterday. They haven't been there more than a couple of days and look like they're in decent condition. I'll guide you to them but I have NO way to move, store, or ship them. They're in rack mount size cases that are about 30" high and they have a wood looking top on them.

There are three flavors of Documation interfaces: parallel
differential, parallel single-ended and serial (Cardamation). I
believe the M1000 only came with the differential interface. I
have an HP-branded M600 (HP2983A) and it also has the
differential interface.
I'm in the process of building a Documation to USB interface
based on a Ubicom/Scenix microcontroller and the FTDI parallel-
to-USB chip. Have the parts but haven't had time to get started
on construction. I'll post the schematics and code hopefully
within a month.
Dang it Sellam, your M1000 slipped under my ebay search
radar because it's a "ballot card reader" not a "punched card
reader."

Is there anyone in the Boston area or near the east coast that wants to
make a little money with their old iron?
There is a production company doing a documentary and needs a PDP-8
(straight) for their project, as well as a PDP-1.
I am not aware of any PDP-1's out there, but I remember there is at least
one PDP-8 in those parts.
If you've got one and can stand to lend it out for a day or two, please
contact me and I'll give you the details.

A year ago I acquired a Southwest Technical Products Corp. CT-1024 TV
Typewriter II. It was a basket case. The main board was purchased as just a
bare board and the original owner had used what ever parts he had. (SWTPC
clipped a corner on bare boards they sold without a kit of parts.) The
keyboard was an old Keytronics unit.
I wanted to restore it to "factory" condition. My brother had just given me
a nice Metcal soldering station so stripped the main board of all parts and
only lifted a few pads.
Over the next 6 months I collected a complete set of parts. In the last
month I got serious about this project and I have finished except for a new
clear acrylic plastic case.
This unit is now closer to "factory" condition then when it was assembled in
1976 or 1977. All of the ICs are the correct part (7474 not a 74LS74
substitute.) The capacitors new but are the same type as the original. They
tend to be smaller in size then the 1975 versions. I was able to get all new
Molex connectors.
There was a recent flame war on what is new and what is original but I think
this restoration improved this classic computer terminal.
Here are some links to my CT-1024 TV Typewriter II pages.

Well, maybe not then...I don't know Penske's rules. However, as was
pointed out, being non-incorporated and doing the above scenario above
certainly is legitimate business, as long as the taxman gets his share
(Schedule C, I think? I don't do it anymore, since I incorporated. Anyway,
that is what accountants are for). No license is needed, at least in some
states.
I would think, however, that Penske would want to see some sort of
legitimate business paper if it can't have an EIN.

Exactly, so you could actually think of the business rate as "normal" and
the personal rate as "built in insurance".

I'm working on a rather large project and am looking for the following
computers and hardware:
Sellam Ismail Vintage Computer
Festival
Some time ago i requested documentation and/or software for my yarc boards ...
... unfortunately, i made no real step forward until now ...
The first board is a quad transputer board, according to a whitepaper, i got from
Ram Meenakshisundaram, which identifies the board as the "Yarc ProTran".
The board should run Inmos B004 software, but i had no success, maybe one of
the numerous jumpers is placed wrong ...
The second board is named Yarc sprinter, it contains an AMD 29000 processor ...
i found a reference to MiniMon29K, but a request to AMD was not successful, they
redirected me to Embedded Performance Inc, which support the AMD 29K family,
but the request was not answered ...
I tried to contact Trevor Marshall, but got no response too ...
... it would be nice to get those boards up and running, so any hint would be very helpful !
Thanks

Yes, it's the exact equivalent of an RD31. Only works on an RQDX3,
though (not RQDX1 or RQDX2).

Thanks for all the pinouts, I tried them all
and a couple more variations and still no luck.
I'm not familiar with RS/6000 systems, perhaps
I should not be expecting a console to appear
because of the c20 error.

That is EXACTLY how my "company" got started. I wanted to buy some parts
>from someone that only sold to businesses. So I made up a company name
(Myth Technologies... because the company itself was a myth), printed
some business cards in HS Graphic Arts class, some letterhead on a laser
printer and bought my parts.
I later used the business cards to start getting extra stuff at computer
trade shows... and eventually when I did start doing part time
consulting... it was just natural to keep using the same name. (Today I
actually have to declare the company on my taxes)

Hello again,
Does anyone have a spare (working) UK-spec telephony module for the ICL OPD
and/or Merlin Tonto that they're willing to part with?
I can swap it for one which "sort of" works: you can receive calls with it
(on either line), but it doesn't seem to like dialling out. Specifically,
it seems to work when its cold, but after warming up for 1/2hr or so, it
refuses to make the proper dialling noises, pressing the buttons just seems
to cut the line for 1/4second or so, then the dial tone is back...
Willing to pay postage from wherever, and maybe 75p & a packet of rolos
(aka comp.sys.sinclair standard purchase price) as well.

Hi all,
I'm now starting on the Jupiter Ace again and I've got one really big
question that's been bugging me for a while. How the heck does the Jupiter
Ace display *graphics* on-screen? It looks like the chargen is text-only and
there's no way 256 characters can cover the entire screen. Does anyone know
how Jupiter Cantab pulled this off? My Z80 is *very* rusty - otherwise I
would have disassembled the ROM and found out myself.
And yes, the Ace is well on its way to getting fixed. I need to rebuild
a few vias and replace some IC sockets, but it should work by the time I'm
finished with it.
I also need a 32-ohm speaker, circular, about 1 inch in size
edge-to-edge. Has anyone got a spare for sale? These same speakers were
*apparently* used in some of the Sinclair machines (Spectrum and ZX-series
IIRC).
Thanks.

There are basically three ways to get an ST412-like disk to work on an
RQDXx controller.
The easiest is obviously to use a real (or exact equivalent to) RD5x or
RD3x disk, and format it as such.
A second way is to use ZRQCH? in the mode that lets you specify the
type, and format a disk which is slightly bigger (more tracks and/or
more heads), as if it were one of the supported types. That only works
for an RQDX3 with late(ish) ROMs.
A variation on this for an RQDX1 is to use really old ROMs and a disk
that behaves sufficiently like an RD51 or RD52 (eg has the right number
of cylinders). Not all disks work, and they may stop working if you
substitute later ROMs (real RD51/52 disks are OK, the firware
recognises them and updates the format). The reason is that the
firmware in the RQDX1/2 recognises disk geometries by probing, by
playing tricks with the disks. The earliest version of the firmware
had only very simple tests, and could be fooled (I used to use a Rodime
3.5" drive on my RQDX1), but later firware has more tests (and six or
eight disk types) and if it doesn't recognise the disk, it won't play.
I once exchanged some email with the guy at DEC who wrote those
routines so I have some what they do, but no details.
The third method is to use ZRQCH? or ZRQCG? in the mode that asks all
the relevant questions about geometry and disk type. This only works
for RQDX3s, but if you can work out what all the RCTs, ZBNs and other
TLAs mean, and know how to work out all the numbers required, you can
format anything and call it RDanything. And later versions of DEC OSs
will be perfectly happy. The problem is knowing how to work out the
answers. I did it once, and Tim Shoppa (IIRC) has also done it, but as
far as I know, the full information isn't published anywhere. If you
want to try this, I can look out my notes about the TLAs and how to
work out the type numbers, and look up the manuals to see how to get
ZRQC?? into the right mode (I recall that different versions were
slighly different, if you see what I mean).

Hi All,
I picked up a huge crate o' stuff at the local cactus U auction
a few weeks ago. Among a lot of other stuff were several boxes of
older computer boards One of the boxes contained about 15 or 20
boards, about 12x12", two fingers, that were either 68k processor boards,
DV11, 512k Momory boards (yes, they say right on them...momory)
Most were in static bags that labeled them as Toshiba TDF 500A,
Other boards were 8" and 5" or floppy drive controller boards. A lot
of the descriptions/info were handwtitten in Japanese.
They all seem to be in very good condition, save one, which had the
chips removed, and put in a seperate box.
I did a quick google search for Toshiba TDF500A,
but didn't turn up anything!
Any information on them (besides telling me that they are 68k SBC)
would be helpful. I plan on keeping a set. (although I'm a Qbus/Unibus
guy myself) But the rest are free for the taking. I will ship if you
pick up the shipping/packing charges.
Cheers
Tom
