Hi,
I saw this thread about installing new kickstart roms to A500s and this (probably silly) idea occurred to me: Would it be possible, using some dedicated hardware that translates Rom-signals to whatever-signals-flash-based-storage uses, to use compact flash cards in the place of normal roms (EPROMS?)?
Kinda like the kickflash?
