...but you're right - it's a bargain. I'm going to have to read up on
re-forming electrolytic caps. Here's some other info he sent me:
"The boards are:
- Cromenco Z80 CPU board
- Scitronics real-time clock board
-- The BIOS I wrote for CP/M makes use of the clock but I'll be darned if
I remember how!
-- Probably needs a new battery
- A serial/parallel board
- A serial board that I made (wire-wrapped). It used the 8250 UART which
used by the original IBM PC at that time. A write-up of the board's design
can be found in the June 1984 of
Microsystems (Sol Libes magazine).
- The Morrow Disk Jockey 2D/B.
--The BIOS was modified so that an 8" double density floppy could hold
about 1200KB instead of the standard 800 or 900 KB. When my friend and I
made the change all the nerds that were our friends were amazed and
proclaimed that it was all the storage anybody would ever need. Times have
