I've gotten one of these beauties, a lovely pumpkin orange overlay around the keys.? Inserting a battery, it's pretty good? but the 4 and the 6 key just don't work. I took it apart thinking it's a stuck or rusty key but pushing just on the raw Kilxon keypad it's still the same.? I suppose there is some kind of keyboard scanning going on that's not picking up these pushes even though the actual buttons do work.? My previous experiences of opening similar TI thing have been just disastrous.? The keypad is connected to the logic board by 8 or so hard wires that are looped around to fold it into the case.
If anyone has any advice on this please let me know.? Thanks, Jim
Hi! The S-100 6502 CPU boards are with their builders and seem to be working. John has written up a page on S100computers.com on bringing up the S-100 6502 CPU board.
http://s100computers.com/My%20System%20Pages/6502%20Board/6502%20CPU%20Boar…
We are incorporating the changes necessary for S-100 6502 CPU board V2 to be IEEE-696 compliant with TMI circuitry. The changes necessary are quite extensive. However, if other builders would like to make further changes please contact me. There is a large prototyping area on the V1 board to support the new circuitry.
The schematics, PCB layout, parts list, and test software other information is on the N8VEM wiki
http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder <http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder¶m=S-100%206502%2…> ¶m=S-100%206502%20CPU%20board%20V1
There are still plenty of the S-100 6502 CPU board V1 PCBs left so if you would like one or more please contact me. They are $20 each plus $3 shipping in the US and $6 elsewhere.
Thanks and have a nice day!

Does anyone want a Decwriter LA36? I've got one that I'm willing to
give to anyone who will come get it (or pay for shipping, although that
would be expensive). As far as I know it works although it hasn't been
used in years. The one problem I know of is that the 20 mA interface
was blown out in a lightning storm sometime in the 70s, but the EIA
interface worked the last time I tried it. I think I also have some
(perhaps all) of the user and maintenance manuals for it. I also have
an acoustic coupler if you want the true 1970s experience. This is
located in Ann Arbor, MI so it would be easiest for someone in southern
Michigan or northern Ohio or Indiana to come get it.

In the middle of 1980s, I was user of Intertec Superbrain computer:
http://en.wikipedia.org/wiki/Intertec_Superbrain
I found information about it on Dave Dunfield website:
http://www.classiccmp.org/dunfield/supbrain/index.htm
I still own it, but original diskettes came with the computer are lost.
(it was CP/M maybe 2.x but not sure, some BASIC, etc) I found also list of
CP/M OS images on Dave's website, but I'm not sure: which one could I take to
boot Superbrain?
I thought, different CP/M machines have different port mappings or...?
And how it is possible to write images to floppy diskettes on PC computer so that
Superbrain can boot from them?
Need 232 to 60 & 20 mil loop converter thanks

Hello Edzard...
Let me introduce myself first... My name is Paul, from the Netherlands.. and I'm building the Old Junior Computer from Elektor... The computer is already up and running and now I'm busy with the floppy card.... Final step is a memory card ... The goal is to have the DOS -Junior combination back running... But I'm looking for a version of OS65D...which is very hard to find... Maybe you know some entries where I can get a version of this Operating System....V3.3 of the OS would be nice...
Many many many thanks in advance,
Paul Moers from Netherlands.
Hi Guys,
I saw that someone was looking for the disk to go with the TRS-80
Model 100 Disk-Video Interface ...
This is available on my site.

So a brief truck trip to Maryland netted some really great stuff from
an old friend. This is stuff I'd seen before, but he surprised me by
saying "hey, bring a truck!" ...so I did, and here's what I came home with:
IBM 029 keypunch station, complete and in excellent condition
DECsystem-2020 (yes, another one!)
DEC RM03 14" disk drive (aka CDC 9762), but sadly no disk packs
DEC TU45 magtape drive, in pieces but likely repairable
DEC LA120 printing terminal, dirty but in good shape otherwise
VAX 8350 w/Unibus, Unibus SCSI, BI-bus SCSI, and CIBCI
A few other DEC items, RL02, RX02, small PDP-11/23 system
A commercial deli slicer (for my chef fiancee')
