I just picked up an Anderson Jacobson (Model: AJ1235) acoustic/direct
coupled modem. Anyone have any information on this?
QUESTION #1:
The front panel has a slide switch that is labled "Disconnect" and has ON
and OFF positions.
There is also a momentary push button labled "connect".
Now, I assume that the "Disconnect" switch is to pick-up and release the
phone line when the direct coupled plugs are used but, what does the
"Connect" button do?
QUESTION #2:
There is a 300/1200 baud switch. all of the acoustic modems I have ever
used only ran at 300 or slower. Can you run 1200 baud over an acoustic
coupled modem?
QUESTION #3:
The place I bought this at has a few more. Anyone interested?

Subject: PDP 11/23 System to go (Long Island, NY)
I have an 11/23 system that needs a new home. It is actually a complete
IMAGES system as sold by CGL,Inc. way back in the the early eighties.
It runs a legit flavor of UNIX off an RL02 diskpack. The bundle consists
of three wheel-around racks and a few loose items. Rack #1 is the CPU
and two mounted RL02 drives. Rack #2 contains (3) Genisco frame buffers
and power supplies. Rack #3 contains a video patch panel, sync
generator, RGB->NTSC video encoder, NTSC->RGB video decoder and a video
digitizer.
In addition, there is a VT100 terminal, a large graphics tablet, a third
unmounted RL02 drive and a cabinet rack with over a dozen RL02
diskpacks.
At this time I would prefer to unload the system as a package rather
than break out individual components.
Interested parties must be prepared to move system. I will not ship.

"nobots_" from this address: larry(a)nobots_cdknet.com

Hummm. Well I think form and function are related.
My thoughts would suggest...
NorthStar* Horizon (wood cover) as a simple but pleasing to the eye design.
Kaypro Toteables, very functional and simple.
DEC BA123 based machines for simple styling and good mechanical/thermal
engineering.
Epson PX-8 laptop. small package for its time but not industrial looking.
TRS80, TI99, Commodore C64/C128 for evolving the wedge design to the limit.
Others, PDP-10 (KA10), PDP12

If that is a "LOGIC" it could be a scsi controller. Logic made a 5380
compatible/and better controller to the ncr5380. You should see the number
somewhere on this chip "5380" or similar.

Kai's original Top 150 list had the AT&T Unix PC 7300 on it.
I passed one of these up in a junkyard a few months ago. It looked a bit too
much like a terminal and I didn't know anything about it.
Did I do wrong?
My decision was a little swayed by the fact that I powered it up without
looking and something went bang. It was then that I saw the 110v sticker on
the bottom. We have 240v around here!

Greetings to all,
I was wondering does anybody have a keyboard to fit either of these
computers (a Sanyo MBC 555 or a IBM 5150 XT) and would like to sell it?

Today, I found a mint Epson HX-20 at the MIT hamfest. All the
original packaging and manuals, and only $15. It doesn't have a tape
drive or expansion module, but it's cool nonetheless.
Anyone know where to find software or monitor documentation for this
thing?

Definitely it was the Star. My ex worked at Xerox from '85 through '87.
Some details in "Pirates" were, um, a little "inaccurate," but they got one
thing right -- there were a lot of really pissed off people at Xerox when the
Apple GUI hit the streets.

Hello, all:
I just finished watching "Pirates of Silicon Valley" on TNT, an
interesting interpretation of the dynamics between Apple and Microsoft from
1975 to 1997.
Here's the question -- what was the name of the computer at Xerox that
Steve Jobs "modeled" the Lisa/Mac after? Was it the Alto or the Star?

Hmmm, now this doesn't look particularly good.
I manually pushed the carriage to the right and it worked. (ie the pawl
re-engaged.) Then I typed for a while and then it stopped spacing in the
middle of the page. Manually push it one character space and it works again.
By observing the mechanism, I can see that there is one position of the
spacing ratchet that doesn't seem to allow for spacing. It could be a
broken tooth but I can't tell from looking at it from the side. Another
interesting tidbit is that when I hit "return" the carraige _stops_ at that
tooth, even if this means stopping mid page!
Now a damaged tooth could be used to explain the first behavior but not the
second I don't believe. The cardboard/spacer thing is still in there and it
doesn't seem to harm anything so I still can't tell if it is supposed to be
there or not.
I have a complete (but dirty) typing unit available as an organ donor if I
can deduce the cause of the trouble.
--Chuck
Spacing Ratchet shown on page 75, part number is 181077 for the gear at the
bottom of the spacing ratchet, it apparently attaches with two bolts, the
carraige stops when the feed pawl is lined up with one of the two bolt
heads on the top.

I have a question for you and the other EU subscriber (in future hopefully
will ask the same to U.S. subscriber):
What is the Bigger/Better HAMFEST relating to RETROCOMPUTING swap/trade in
your country?
Here in Italy I think is in PORDENONE (30/04 -> 02/05)
Is Friedrichshafen the biggest HAMFEST in Germany (or even the biggest in EU?)?
And what about France, England, Portugal, etc.?
I'm tryng to organize a "RETRO-EXPEDITION" from Italy to Friedrichshafen,
and would like to receive infos on this and other EU Hamfest.

I'd spotted the rack Jim mentioned yesterday in my wanderings before he
posted about it here, and today I decided to go pick it up. Good thing I
did, as I was out in front of the store, pulling the drives out of it so it
would be easier to handle, I got to talking to this old guy. We got to
talking about old computers, and it turned out he had a card reader he
didn't want/need any more.
So I went over and picked it up. It's a nice small unit, that can easily
sit on top of a desk. The only problem is I'm not sure how to interface it
to anything. It was made by "Peripheral Dynamics Inc", and is a Model C302
manufactured in May of 1972.
I think you're supposed to interface it by plugging some sort of card into
a connector in the back of it. Unfortuantly he didn't know where the
manual is, or if he still has it. Does anyone know how to hook one of
these up to anything? Ideally I'd like to be able to attach it to a Unibus
system or a PC.

Hello everyone, I'm bringing back to life a "LT33" (aka a DEC modified
ASR-33 teletype) and out of the gate I've got an issue.
When I switch on, into "local" mode, I get continuous "nul" typing. The
mechanism is doing the typing dance and its trying to type NUL. Where to
start? I've got the prints and am going to check out the keyboard area for
now, perhaps it has a clue.
I'm guessing it is either stuck in 'here is' mode, the keyboard is sending
infinite nuls, or something else :-)

ever seen a Lear Siegler ADM 5 terminal? I have one and it's cool. The iMac
looks a lot like it in terms of curves. Just because you don't particularly
like something doesn't mean it has to be "grotesque" or "gross" or some other

A few days ago, I was in a local used electronics/Junque (only
high-class stuff here :-)) and found a rackmount case with PS, SCSI
cables, and three devices for five bucks. Took it home, blew the dust
out, and found I'd gotten a Exabyte 8mm tape that worked perfectly with
my VAXCluster (once I'd reseated the cards, blew the dust out and ran a
cleaning tape through it), an Archive 160 meg QIC drive (have no use for
this, anyone want it?) and a 5.25 in floppy with what claims to be an
NCR SCSI intereface bolted to it. It's this last I need info on.
This interface board is the same size as the drive; at one end is the
power plug (it appears to be powered independently of the floppy) and
the SCSI header. The other end has a 34 pin header with a standard cable
going back to the 34-pin edge connector on the floppy. Has an NCR 5380
and an Intel 85272 as the main chips, with a lot of glue, as well as a
80188 CPU with ROM. There are two switch pack, one 4-pos, one 8-pos.
The 4-pos pack has the first three positions labeled FT and the last
position is labeled EXT PF.
The 8-position pack has the last three switches labeled ID (almost
certainly the SCSI address). Anyway, anyone ever seen one of these
before? I'm a little scared to just plug it in; I've seen lots of tape
drives but this is the only SCSI floppy I've ever seen, and I want to
take good care of it :-). Any info greatly appreciated.
Thanks in advance!

As far as aesthetic appeal goes, to my taste absolutely nothing beats
a Cray-2 !! Next would be the CDC 3000 series with its tinted glass panels,
next the Cray-1. (Ranking according to my personal taste, of course).
There are quite a few more aesthetically interesting
supercomputers; maybe if you spend so many millions of US$
(and in particular since buying supercomputers is or has been mostly a
prestige matter) aesthetically pleasing design can be expected.

Right.

I have a Quest Elf that I built from a kit as a kid. It was the Popular
Science design, pre-1861 video chip. It has a speaker, a Q LED, 8 toggle
switches for data, DMA/EF4 pushbutton, RUN/LOAD/MEMPROT toggles and the
original TIL311 latching hex displays. My PCB is rev 2.1, 1979. I bought
just the PCB and assembly plans for $35 around 1980. The entire kit was
available for $99.
> > You could say "ELF II/Super ELF".
The Elf II was a different manufacturer, Netronics, IIRC. Quest made the Elf
and Super ELF.
> It should probably say RCA COSMAC VIP, as I have several of them.
Right. An entirely different beast - keypad, ROM, 1861 video, I/O expansion
slot, up to 4Kb on the board, system expansion slot, cassette interface. I
have one, too.

The 7900A platters are 50mils. So that I can keep an eye out for cartridges

were much more common, but don't know for sure.
