PS: The old Micromation floppy controller (CP/M 1.4
days) used NEITHER
chip family, did their own formatin LS TTL, and practically no one can
read them.
I have a Micromation Doubler in my CASU Super C (S100 bus CP/M machine).
From what I rmemeber the single-density (FM) format is
standard, and can
read/write IBM3740 disks. The double density format, though, is
probably
unique to this card.
You can probably do all this in a PC sound card these
days!
Not many sound cards will handle 500kHz signals, surely?
