I have a 512K Mac (Homebrew) which currently has ROMs which will only allow me to have 400K drives. a) Is there an upgrade for the ROMs to allow 800K drives? b) can I use EPROMs (27128) in place of the ROMs by changing chip select lines or something similar? Any info on ROM chip select lines, data lines, address lines would be appreciated.
