Hi
Is there still interest in the board below?
It looks like a simple CPU board and would not be hard to do or at least
make some prototype boards.
Unfortunately this discussion occurred while I was away and it looks
like I missed the entire thread.
Is there a final design? I am assuming the one S100computers.com is the
one the builders want.
I read something about a UART but I don�t see one on the schematic.
Sorry to reopen this old thread but I totally missed this one.
Can someone catch me up with the Reader�s Digest version of where we�re at?
Thanks and have a nice day!
Andrew Lynch
PS, a picture of the prototype board would help too if its available.

Hi Don, just added the link. See here:-

Andrew do a batch run. I�m good for 3.

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...
Good work!!
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 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,

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
