As I don't have a logic analyser to help me with my analysis of the MFM
interface, can anyone tell me how the MicroVAX 2000 determines disk size? I
know it is related to the number of heads, but what does the drive do when
the host asks for a head that does not exist? How does it report this back?
The only thing I can think of is the Ready signal, could that be it?
Regards
Rob
