- OK, for all of you people out there with Apple ][ disk drives, why
- don't 5.25" High Density disks work in the drives? Is it because the
- recording media is different, so it necessitates a different recording
- bias?
-
- BTW, why do 5.25" DD disks have hub rings and HD disk don't? Is it
- done this way so that you can tell them apart?

- ObHack: Needing to convert BCD to floating point on an 8051. We had
- an extra 20K of ROM, so we made a giant lookup table. Then we
- discovered that we didn't need to convert it on the 8051 after all.
