Crusty
could you send me your real name, and if you wish I will
update the entry.
Hi
John,
Were you able to download the zip file for the 8080 CPU
card?
Did you post it? I want to tell Jack where to find it.

Hi John,
I don't have an account to upload it. I'll try
emailing it directly to you, and if you would please
do me the favour of uploading it for others, I would
be very thankful.
Cheers,
Josh

Very
nice Crusty, would be interested in seeing the
schematic. One day I had in mind making an
S-100 debugging board – a kind of board that
would systematically test/debug some of the
S-100 lines one at a time. A PIC may be the way
to go, though I am also curious what the
Propeller II will look like.

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
