Hi Tom,
Very good idea's.� I'm getting my ALTAIR in a couple of
weeks, so I can work on interfacing the FP with it.
Q? What is the standard 10 pin header for PC style DB9?�
I've seen 2 pin outs.� One where the wires are matched pin
for pin, another where the wires are matched based on the
IDC connector of the DB9 (which puts pin 6 between pins 1
& 2).� Perhaps we provide two 10 pin headers?

If we do a PWB and build
this board, I would like two of them....
I would like both the IMSI and ALTAIR front panel
connector on the board....
Serial
port should use standard 10 pin headers to allow
connection of standard PC style DB9 cables...
Thanks....

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

directly to you, and if you
would please do me the favour of
uploading it for others, I would

IMSAI 8080 CPU card
replacement

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
