Tim_axe: I was going to suggest switching the boards, but economically its pointless as your going to have to spend money on new disks and then make 1 lot unworkable by removing the board.

I think buying one and copying the eeproms is good solution, building an eeprom copier isnt difficult once you have the data sheet.

Im sure this isnt the simplest solution and would like to see what nihil's solution is...shame theres so many crooks about your worried about people stealing computers to share it in the public domain
