Hi! The S-100 6502 CPU boards are with their builders and seem to be working. John has written up a page on S100computers.com on bringing up the S-100 6502 CPU board.
We are incorporating the changes necessary for S-100 6502 CPU board V2 to be IEEE-696 compliant with TMI circuitry. The changes necessary are quite extensive. However, if other builders would like to make further changes please contact me. There is a large prototyping area on the V1 board to support the new circuitry.
The schematics, PCB layout, parts list, and test software other information is on the N8VEM wiki
There are still plenty of the S-100 6502 CPU board V1 PCBs left so if you would like one or more please contact me. They are $20 each plus $3 shipping in the US and $6 elsewhere.
Thanks and have a nice day!
