Hi John.
I'm posting this message to the Classic Computers mailing list to let
other people know about this cool project.
If you are having problems with bandwidth limitations, talk to Jay West
<jwest(a)classiccmp.org>. He runs the CC mailing list and offers free
hosting to people with vintage computing projects.
For all reading, John's 4004 Tic-Tac-Toe project website is here:

Check it out...it's VERY cool.

Does anyone know exactly what this
<http://home.cfl.rr.com/rigdon14/microrobot/box.jpg> is? I found it in a
pile of surplus material yesterday. It appears to be a computerized
controller for a robotic arm. The box is marked Microrobot Motor Mover.
Inside it has a large circuit board with a 6502 CPU, two 68B05 MCU ICs, a
6522 VIA IC and an EPROM and two external DB-25F connectors. It looks like
a complete microcomputer controller that can be controlled by a computer or
via the front panel. There's also a daughter board that sits on top of the
main circuit board. It also has two Opto 22 OAC% solid state relays that
appear to control the AC sockets on the back of them box. Around the large
hole in the main board, there are a number of connectors that have cables
that run to the back of the box. The connectors are marked Wrist (2 each),
Grip, Elbow, Base and Shoulder.
I've posted more pictures at <http://home.cfl.rr.com/rigdon14/microrobot/>.

My question, though, is what's the alternative to PC-based test equipment?
Completely self-contained proprietary stuff?

I'm of the Tony Duell school here.. Document as much as you can if you care
about using it in the future.
The PC stuff is 'proprietary' as well, with the exeception of a few card
vendors, you can't find out from them how it works (or doesn't...)
Any instrument with a microprocessor should have its ROMs read and backed
up. I got VERY lucky and was able to get my 16500B analyzer going again
because I had access to another unit, was able to read the eprom, and was
able to reprogram the part that had gone bad (a bit had gone to a '1' and
could be reprogrammed to '0')
The entire CPU board is a FRU, it's cheaper to find an entire chassis on
eBay than trying to find just the processor board.
Hello,
some time ago, i asked for a manual of the TI-52 calculator in a message board
Do you still have such a manual?
If yes, would you be so kind and send a scan to me?
That would be really great!
Thanks a lot

I don't want to see this stuff on Ebay. If it was going to make money,
I'd put it in the Christmas fund, or give the equipment to the local
computer recycling project. The reason there are no PCs or other
common items is that they're going to an African charity project.

It's not cool. Everyone thinks they need 100Mbps at least, or
preferably Gigabit. The fact that their PCs mostly can't keep up with
that seems to be immaterial, as is the fact that their web connection
is hardly likey to keep up with the PC. On the other hand, many of our
students in residences love it -- it's 20 times what most of them get

I have a poor quality paper copy.
Local electronics store has a Unisys 9246-7 printer. This is a pretty
big/heavy animal. I'm sure it's made by someone else like printronix or
citoh or dataproducts or mannesman, etc. Looks like a band printer, parallel
interface, high volume in a floor standing cabinet. That's all I know.
The guy said he had a buyer from out of state, but the guy doesn't seem to
be following through on the deal so he said it was available. If anyone is
interested contact me offlist and I'll pass on the contact info. The printer
is in St. Louis. No, I won't haul it to VCF, vehicle already full.

by the way... I am not bringing an 11/45 to vcf east :) I was referring to
how it looked when I got it recently from TN. I haven't started on that
restoration project yet, and I doubt pretty seriously it'd get any awards
the way it looks now *GRIN* Well, maybe... "system carrying the most dirt
and grime".
Now, if Sellam would ever have a VCF-Central, in St. Louis, I would bring
the dual bay HP2000/Access system. If it'd be in St. Louis then I wouldn't
mind so much having to tear a wall out of the basement to get it out.
It does look like there is a pretty reasonable chance I will make it to VCF
east. Can't wait to meet everyone! I will most likely be driving from St.
Louis to VCF and back with either a small flatbed trailer, or a van (or
both). Any riders along the way want to come with and share gas costs? It'd
be nice to make the drive in one stretch, doable with multple drivers.
If anyone going to VCF east wants any HP racks, 13037 controller systems, or
7906 disc drives, now is the time to speak up cause I'll bring it all with
me. Could bring some 21MX's too.
Regards,
Jay West
Hey, anyone else here from the city? At 9:00 tonight I'm meeting some VCF
attendees (including Hans Franke, all the way from Munich) at the bar of the
Carlton Arms hotel (160 E. 25)... if anyone's around, call my cell phone,
617.461.7194.

Anyone have a 21MX M series box I can borrow parts from for a bit? My M
series machine is sick and I'm not sure if it's the front panel or the cpu
board. If someone wants a speed upgrade, I can trade them a E series cpu for
the slower M series cpu/front panel. At the least, I'd just like to see
which one is dead.
