I still have to put the scanner together again (tomorrow night) and do that. I am using Windows XP in VMWare on a Debian GNU/linux x86 host. I guess you mean "try a disassembler", like x86dis, assuming x86 code. It seems however NEC uses something like a V850 a lot. I'll look around. General question: if there is a generic ASIC used to instruct the scanner, does that mean the scanner driver hardware is then off-chip, or can a generic ASIC produce the same kinds of outputs as, say, the Genesys scanner driver chips?
