- Ah, but did you ever experiment to see if you could get *more* than 40 tracks
- off a 40-track drive? I discovered that I had actually gotten one 42-track
- and one 43-track drive. Trying to treat them as 44-track drives led to funny
- noises and read errors, to nobody's great surprise. Those worm gear head
- positioners sure could develop some torque.
-
- This was on the Trash-80 Model I, which got a lot of weird third-party
- support. In addition to the standard 35-track single sided drives, there
- were double-sided drives, double-density adaptors, 40-track drives, 77-track
- drives, 80-track drives, 8-inch drives, and toward the end, 5 MEG HARD DRIVES
- ("now under $2000!"). Step speeds varied by an order of magnitude, and there
- were bytes to change to tune those, too.
-
- And if you didn't like something, you could cut traces, solder, and *fix* it.
- Try *that* with your eight-layer 486DX2/66 motherboard. Sigh...
