Hi
Andrew,
Just thought you would
like to see what I've done
on one of your prototyping
boards.
It's a replacement CPU
card for an IMSAI 8080.
It uses an 8080A and has
the 16 pin socket to
connect to the Front
Panel.
I put 64K of RAM on the
same card and a PIC
microcontroller to provide
Serial I/O, Floppy Disk
emulation on a 8Meg flash
chip and a Boot strap
program.
It can boot up into CP/M
1.4 all on the same card.
I did this because many of
the other cards of that
era are flakey and I
wanted to get the IMSAI
8080 computer at the PC
Museum in Brantford,
Ontario working.
If anyone wants the full
schematic & firmware,
just let me know where to
upload it.
:)J
