These all used standard cables. They have two separate 34-pin connectors for two standard floppy cables (with the twist), two drives on each of the two separate cables. However, 3 of the 5 boards that I had are gone, sold to readers of this list. I do still have two left. One 4-floppy only (8-bit ISA), one 4-floppy plus IDE (requires a 16-bit ISA slot). ************* Important for me would be a cable to go with these. My understanding was the twisted cable worked only for two-drive chains and for more than 2, you needed to either strap the drives individually or make a very specific cable. John A.
