Hi, at the N8VEM project we were working on an S-100 6502 CPU board. It was built as a
wire wrapped prototype and the design has been shown to work.
Since then, we've designed a PCB and have some prototype boards. Most of those have
already been sent to builders. However due to some injuries and other unfortunate events,
those projects are on hold indefinitely.
I still have one S-100 6502 CPU prototype board left. I have high confidence in this
design that it will boot with little or no modifications. If we could get a volunteer to
build and test this board, then I could get additional PCBs for other S-100 builders.
However, without some knowledge of whether the actual PCB really works, I am hesitant to
release it quite yet.
If you are an experienced builder, familiar with S-100, and would like to volunteer to
build and test this prototype PCB, I will send it to you at no charge.
All we really need for confirmation is that the S-100 6502 CPU board can boot with a basic
monitor ROM. There is some sample code available for a notional S-100 6502 CPU board boot
ROM.
Basically, this project is stalled at its very last step and I would like someone to
volunteer to build and test the prototype for confirmation of the design. Certainly this
is not for everyone but if you would be willing to help out I would greatly appreciate
it.
Please contact me by email. Thanks and have a nice day!
Andrew Lynch
