Just a quick note about recent projects, what are you guys working on for
the new year?
I have an IBM Thinkpad with a bad keyboard, I plan to replace and rebuild
I picked up an IBM PS/2 model 70 yesterday but it has a bad (or dirty) disk
drive - working to restore to Windows 386 (thanks Bryan) and DOS 4.0, as it
would have had in the Summer/Fall of 1988 when the 70 was launched. My 70
has 6 Meg. No I am not loading OS/2.
On a more vintage note I have gotten more confident with my ability to
conclusively test various s-100 RAM cards, allocate programs to specific
locations, change memory values, etc using my IMSAI. I can also assign the
memory pages (0000-1000, 1000-2000, etc.) so that there can be more than
one RAM card installed without conflict. I have installed 32K into the
IMSAI. As I identify good RAM cards, I can put some into the SOL-20 I
also have on the table. I have a small pile or RAM cards that I have
accumulated from various places. I also soldered up a cassette cable for
the IMSAI. I broke down and bought a new Radio Shack tape recorder so that
I can count on a reliable drive when testing cassettes on an S-100
system. I have some Altair BASIC tapes that I want to load. After that I
plan to attempt a Micropolis controller card and 2 or 3 compatible disk
drive. The Micropolis cards had their own monitor I believe. Overall, I
am working at being a competent S-100 programmer, and hardware support
person (but not hardware developer)
I am reading about Oscilloscopes, so that I can test stuff at the component
level. I have a book from 1958 that should get me started, and a few old
scopes from Herb.
Next - apple /// power supply and hard drive.
Replace disk drives on Northstar Horizon.
I'll post pics of all this soon.
Now that I have the IBM Series 1 at work, I can sneak out for a break and
work on this thing during the day. If anyone is interested in this system,
feel free to stop by my office in Wilmington, Delaware
...and tomorrow I will...
...Omni Reader (first OCR scanner)
... TRS 80 Flat Bed Plotter (Model 1...Coco 1 era plotter)
I plan to visit InfoAge March 23 anyone else? BOD meeting and museum help
day? I have to plan my weekends pretty far in advance.
