Hi! One of the N8VEM builders is interested in making a JUPITER ACE board. He is making a PCB and assessing how many builders would be interested in the PCB. I have little information on JUPITER ACE but it appears to be a small Z80 based SBC which uses Forth. It generates its own video signal and has a keyboard interface. If you are interested in such a board please contact me or let us know on the N8VEM mailing list. Thanks and have a nice day! Andrew Lynch
