- Every few months I complain about this again. Maybe someday Apple will fix
- this. The floppy drivers provide async i/o, and it would be no trouble to
- command a seek, then use the time manager to poll the drive a calculated
- number of milliseconds later to pick up the data. The driver would be easy to
- write. The application software could certainly use the seek time to good
- advantage. (Quicktime, for example might like to use those cycles.) But
- what apple giveth with one hand in '84 (in the orginal Mac 128k), they take
- away with the other (the SCSI driver has been broken in this way since its
- introduction in '85.)
