Have you verified that these will actually work with a PC with whatever cable you are using? It is my understanding that this is not possible without additional hardware to handle these particular drives.
Your must be right, I 'wrongly' assumed all 34 pin floppy disk controller cables were based on the same standard. After some digging I found that the SA400 use a slightly different pin-out supporting 4 drive select signals and 5, 12 VDC on pin 1 and 4. Most other signals seem to be on the same pin. Thanks for putting me on this track, because I still have to do some work on older S-100 systems and FDC's, and I didn't know of this pre IBM PC 'standard'. I will use the Supercard for the PC generation stuff I have.
