My work in progress is already available online: http://cbmrom.trikaliotis.net/ The "ugly" 1571CR changes can be found after $88F0 (cf. http://cbmrom.trikaliotis.net/full/floppyrom.a65.full.html, lines 2371...). Beginning at $89B3 (lines 2526...), it becomes apparent that most differences are because the WD1772 and the 5710 have to be programmed very differently. And: No, I have not done these changes with the linker that I spoke about in the other mail yet. I have done some tests, and I know it is working, but much is still missing. I hope I will be able to come back to this in the not-so-far future. I started this work with the C64/VIC20 sources, though. Regards, Spiro. -- Spiro R.
