Oops... forgot to say that in the schematics for the external disk drive interface as well as the citizen drive circuitry, the Drive Select A/B pins on the floppy connector and left unconnected (pins 12 & 14)
Do these need to be connected to something to enable the PC drive ? Colin Piggot ==== Quazar : Hardware and Software for the Sam http://www.quazar.clara.net/sam/
