As I have a 40 track drive attached to a UDC card I simply updated the ROM from 35 tracks (280 blocks) to 40 tracks (320 blocks) and I can run completely standard ProDOS and applications with full 40 track support......but what happens if you then insert a 35-track floppy? I assume reading it would be OK, but if you tried to write it, could your patched ProDOS then attempt to write beyond the last (35'th) track?
I presume you'd be fine, since those tracks would not be part of any file nor would they be marked "free". -michael NadaNet networking for Apple II computers! Home page: http://members.aol.com/MJMahon/ "The wastebasket is our most important design tool--and it's seriously underused."
