How many different disk drive controllers did Radio Shack/Tandy release? I
think there are at least 5. Two long ones numbered 26-3022 and 26-3029, as
well as three short ones numbered 26-3129 (FD500), 26-3131 (FD501) and
26-3133 (FD502). Were there significant differences between each of these?
Were they renumbered because of ROM differences? I think the long vs. short
had different power requirements (12v vs. 5 v?).
