Hallo allemaal,
It seems I have managed to squeeze all my 1541LPT routines inside the
JiffyDOS ROM as well, although not tested yet. I also worked out a mechanism
that enables a user to ask the PC what D64 images are available. If all this
works out fine, I think I can present 1541LPT as version 1.0.
The next step is to go beyond the 1541 limitation. The first part of the
solution is quite simple IMHO: intercept the commands before they are
executed. The only entry point I have found so far is the routine that
starts interpreting the command at $C146. If you know more entry points,
please let me know.
The second part is more difficult: handling the 'communication' with the C64
(or other computer). 1) Data has to be sent to C64. The problem is finding
the location of the routine(s) that take care of that. 2) Data has to be
received. At what point must I intercept it?
Any info you have is welcome as well!
Many thanks in advance!
