By eye, I guessed that a Zorro III board could hold 96MB of 1MBx4 ZIP chips. 19 such cards would fill the 1.75G address space. Would a 20-slot backplane have any chance of being reliable? (I mean an A3000 motherboard in a different case, with a 20-slot backplane replacing the standard 4 slots). If necessary the backplane could connect to the motherboard in the middle and have 10 slots on each side. A fully loaded system would cost in the $.3-.5 million range. hehe. But it is amusing to think about... I certainly can't think of any other less-than-mainframe machines that support a large address range both in software and logical hardware, AND have a chance in hell of physically attaching such hardware.
