well ive never ran into one instance of software incompatibility except between 68k/powerpc, but thats a big duh on that part. hehe.

it might have been mac128k or bunsen that may have mentioned software compatibility issues between plus and older macs. but dont quote me on that, i just remember reading a couple threads here where that was mentioned. but otherwise, im going to use plus ROM flashed into a custom board of mine for SCSI. of course it isnt "legal" to do this, but what do i care? just a hobby ya know.
