Lines: 19 One good argument for having an IBM-type bus is the huge variety of hardware add-ons that are available for this standard. I don't imagine that it's not all that tricky to translate the amiga's 68000 bus signals into those appropriate for IBM peripheral cards, with suitable compromises (such as a wait state or two, and not mapping the entire 68000's address space onto the IBM bus). Even accepting the restriction that IBM peripherals with resident ROMed firmware couldn't be supported, I would imagine that a great many useful pieces of hardware would remain, and would then be supportable via the appropriate Amiga software. If the bus translation electronics aren't too tough, mightn't it be worthwhile to add them to an A1500's motherboard? Kind of a brainless built-in "FootBridgeBoard". Out of ignorance: Postings!
