Hi Todd, Thanks for your offer of co-ordinating the ordering and distribution of the prototype PCB, much appreciated feel free to add yourself to the PCB order in case no one picks up the x86 platform (you may have time later) So far we have, Fabio x 1 (6502) Yoda (Dave) x 1 (68K) Me x 1 (Z80) Todd (PCB Procurement) John, are you still willing to do hardware support if we run into a brick wall with the board, if so how many PCB's do you need ? regards David Fry
