Does anyone have the programming pod for a Link Computer Graphics CLK
3100 or 6100 programmer? I have the rest of the HW and SW but I'm missing
the pod. Here is a couple of pictures. They're small but they're all that I
could find. <http://www.linkins.com/devpro.htm>

Ah jeez, it's just a 8 bit video ADC. TRW made more than just
multipliers (they were famous for making 8x8 and then 16x16 hardwired
multipliers). Also famous, a single chip correlator. Details are in
the TRW Databook (now deceased).
But the price on epay is just amazing.

I've posted a pair of pages from the "HP 64000 System Overview" manual
(64980-90912, February 1982) as a 63K PDF at:
http://www.bcpl.net/~dbryan/dropbox/64000-extracts.pdf
They have illustrations of the 64100A and 64110A mainframes and a short
list of their physical differences. (The overview manual seemed to
illustrate these better than the installation manual, once I had checked.)

Hi,
saw the following on alt.sys.pdp11, it's too far away for me :-(
would take the consoleprinters myself if this were in Munich...

I was under the (possibly misguided) impression that Mentec owned or
exclusively licensed the rights to much of the PDP-11 IP. Dunno how
vigorously they would enforce it these days, but they do sell reimplimented
PDP-11 hardware (http://www.mentec-inc.com/Mboards.html).

I made a major score of 1802s recently. A couple of weeks ago I went a
scrap place and found some old traffic controllers. I opened one and found
that they all used socketed 1802 CPUs. I pulled over 50 of them :-) The
controllers were Transyt moddel 1800s and they're made in Tallahassee
Florida. Here is a not so good picture of what they look like
<http://www.signalfan.freeservers.com/controllers/transyt1.htm>. FWIW I
also found a couple of Eagle controllers and I checked them, they used
68008 CPUs.
OK, Now go find those controllers!

I posted several images from my bubble memory collection. I will be
posting better images and more historical information shortly. I have
a nice Sharp module too, but couldn't find my image of that. The URL

Last night, I took the drive apart and checked it out (all looks good), I
could see a rectifier on the input, so I concur that it is AC.
I cobbled together a 9V ac supply and powered it up - I did observe exactly
what you indicate, the drive comes on, spins, and the head steps out and back

If I connect the drive to a computer, I observed the following:
With not disk in the drive, the computer rapidly issues "Boot error" messages
continuously, and the drive remains stopped.
With a disk in the drive (not an Aari disk), the drive activates, and the
computer issues "Boot error" much more slowly - clearly it is trying to read
the unformatted disk.
So - I think the drive is working.
I was unable to find any way to get the system up with the drive connected,
so I don't see how there could be DOS in ROM as some people have suggested.
Any ideas? Is it possible to do anything with the disk without a DOS boot
disk.
This sounds like a very simiar arrangement to the C64 1541 drive, except
that the commodore boots "normally" in BASIC and you can send commands to the
drive via BASIC file operations - the Atari appears to want to boot from the
drive before you can do anything.
I'm planning to build a SIO2PC cable as soon as I can dig up an extra Atari
peripheral cable.

Hi Everybody, (Hi doctor Nick)
Picked up some more old Atari equipment at a flea market this weekend,
among other things, I got a 1050 disk drive. I have not had one of these
before.
#1) Can anyone tell me the power requirements of this drive?
(voltage, polarity, current) - this information should be on the label of
the power supply - as you probably guessed, I did not get the supply with
the drive (had an Atari computer supply in the box).
#2) The box says "Includes DOS 3 Double Density Disk Operating System", but
there were no diskettes in the box at all - presumably I need some sort
of boot disk... Anyone out there with one that can make a copy or send an
image (Can Atari images be read/written on a PC's drive?)
Any help would be greatly appreciated.
Regards,
Dave
