Improvements

  • Added support for "GETCLAMP" workaround, documented in the Apple II Technical Notes. (Read access to mouse CLAMP boundaries was documented, using a previously undocumented "read slave controller memory" command. Only the memory locations of the clamp boundaries were documented.).

Fixes

  • Corrected byte-order of parameters of POSMOUSE command (set mouse cursor position).
  • Corrected behavior of VBL interrupt: can be enabled individually, without the global enable flag.
