ProDOS 2.4.1 Fixes for Apple //e Card

Bitsy Bye as shipped with ProDOS 8 2.4.1 has some bugs related to the Apple //e Card for Macintosh LC. I came up with fixes with the help of John Brooks and produced a fixed version that addresses the following issues:

  • Bitsy Bye crashes the machine because it accidentally accesses $C029 when it is not supposed to. This switches in an extra firmware bank on the //e card, causing a crash when Bitsy Bye tries to use a ROM routine that is no longer there.
  • Bitsy Bye fails to work properly when AppleTalk is installed in the //e Card environment due to putting a ProDOS parameter block in the zero page above $7F. See TN.PDOS.22.
