IBM FSU Static RAM Board...for S-100?!
by Systems Glitch 21 Jan '16

21 Jan '16

This has to be one of the most unexpected S-100 boards I've acquired. The seller says this was created due to the need for denser RAM boards for IMSAI 8080's at IBM's Advanced Systems Development Lab in Los Gatos, California. Apparently FSU RAM was the densest static RAM available at the time, and of course they had access to it, being IBMers. Extra boards were produced for engineers with S-100 machines at home. I wrote up what I know about the boards here: http://www.glitchwrks.com/2016/01/20/fsu-ram Fortunately they came with a copy of the 3-page manual and a (very faded) blueprint copy of the schematic. I've digitized both and made them available. I've tested one of the boards so far, which works fine with my IMSAI 8080 and a 2 MHz 8080 CPU board. I'd be interested to hear if anyone else knows anything about these, or has one, or has spare FSU RAM modules they'd be interested in parting with. Thanks, Jonathan

OT: Dell Dimension XPS 466V
by Herb Johnson 20 Jan '16

> Working on a Dell 486 computer. I need a RTClock battery, but otherwise > it's running quite nicely Windows for Workgroups 3.11 The question of batteries is on-topic IMHO. Batteries in the long term, cause corrosion of parts that have constant current on them. This is true all the way back to 128K Macs. also, many batteries leak (not coin cells), that's not good either. If you add a battery pack, make sure you can readily pull it out when the computer is in long-term storage. Windows for Workgroups (Win 3.1 + networking) is worth preserving. It's a legacy OS now. It ran for many years in embedded applications (back ATMs) and Microsoft support only ended several years ago. Many consider Win 3.1 the first really "successful" M/S Windows OS product. If I had time and interest, I'd see about migrating Win 3.1 to the Heath-Zenith Z-100. That's a S-100 system that is somewhat IBM PC compatible. I don't recall if Windows was offered for that platform, later Zenith PC's ran even earlier Windows (I have those distributions). Herb -- Herbert R.

Please contact me if you would like additional info or to make an offer on any item. I wont bring this stuff unless someone wants it. I would prefer not to ship these items if I can avoid it so the workshop attendees are going to get the 1st shot. Anyhow, here is the list: Vector S-100 Protoboards w tinned edge connector $12 S-100 Cromemco ZPU Z-80 CPU - tested with my IMSAI - $90 S-100 Cromemco TU-ART 2 port serial TMS 5501 based -$60 KSR33 Teletype (complete, case has cracks) $200 ASR33 Print Mechanism with paper tape punch $100 $250 for the above pair Franklin ACE 1000 (needs KB rebuild) $50 Franklin ACE 1200 (needs KB rebuild) with ACE-80 Z-80 card & 1 operational drive $80 Atari 400 with 15 cartridges, power supply & joystick tested working $50 Atari 1050 Floppy Disk Drive w/power supply tested - working $30 $70 for the above pair Okidata 120 Printer for Commodore systems (VIC-20,C-64,etc) with power cord, manual & interface cable $5 Apple Color StyleWriter Printer with power supply $5 Apple CD300 external SCSI CD-ROM Drive with 25 to 50 pin cable, terminator & 3 caddies $ 30 CD-Rom caddies 3 for $5 HP ScanJet 6100Cse 8.5 x 14 flatbed SCSI Scanner - New in box $50 HP LaserJet 4Plus tested working $30 HP 54201D 300mhz Digitizing Oscilloscope w/ manual on CD & 3 10271A state probes/triggering pods $100 Tenma Model 21-7935 Temp.

FS: Cromemco PRI S100 Printer Interface NIB + Manual
by Systems Glitch 19 Jan '16

Link: http://www.ebay.com/itm/272110179325 Untested as I didn't want to unwrap it. This looks like it has never been used at all, still in its styrofoam sheet with plastic overwrap. The original manual and a 25-pin breakout cable were in the box with it, so I suspect it's the original box. Thanks, Jonathan

Snow and January 23/24 workshop
by Jeffrey Brace 18 Jan '16

18 Jan '16

Currently the 5 day forecast for this area says 1-3 inches of snow for Friday night for the InfoAge area. Not a lot and plenty of time for salting/cleaning of major highways. When we get within 48 hours, that is when we get the most accurate forecast. Anyway, I will be keeping a close watch at the weather and be making a decision by Friday morning as to whether or not to postpone the start of the workshop.

Friday classes @ VCF East
by Evan Koblentz 18 Jan '16

18 Jan '16

Very few people responded to last week's call for subjects/teachers, so we're taking a straightforward path instead of creative new things. Most classes will be two hours. Some may be double sessions; TBD. We don't yet know if there will be three or four classrooms available. Hoping to find out soon. There will be morning and afternoon sessions, meaning 12 or 16 classes. Tentative topic list follows. These are all tech repair classes, not historical lectures. 1. Apple 1 + Replicas 2. Apple II 3. Apple Classic Mac 4. ASR-33 Teletype 5. Commodore PET 6. Commodore 64 7. DEC PDP-11 8. IBM PC 5150 9. MITS Altair 8800 10. Radio Shack TRS-80 11. Cassette Tape - Willegal 12. PCB Design for Vintage Computing - Willegal If we have a fourth room available: 13. Power Supplies 14. CRT 15. Paper Tape (should immediately follow Teleype on the schedule) 16. Disk Imaging + Drives Topics can change based on who's available to teach, demand for other subjects/systems, etc.; meanwhile I'll contact several list members individually to get the necessary teachers (or feel free to volunteer). Some subjects are repeats from past years.
