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

Hi David,
I'm willing to take on ordering and distribution of the protoype PCBs.
I'd like to sign up for the x86 code as well, but I fear I'm too busy at
work and don't have a good system to test with at this time in any case.
