- #8: Single-Sided 3.5” Media and the Apple IIc Plus
-
- Written by: Llew Roberts May 1989
-
- This Technical Note describes a media limitation on the internal drive of
- the Apple IIc Plus.
- _____________________________________________________________________________
-
- With the exception of the internal drive on the Apple IIc Plus, single-sided
- 3.5" disks are supported on all Apple 3.5" drives, including external disk
- drives connected to an Apple IIc Plus. The IIc Plus internal disk drive
- assumes that all disks have an 800K capacity, so it returns valid reads on
- blocks which occur on the formatted side and I/O errors on blocks which occur
- on the unformatted side. A disk may appear to work when the disk-reading
- algorithm has read blocks only from the formatted side.
-
- For these reasons, we suggest that you do not ship programs on single-sided
- media.
