Although it does not require memory mamnagement, it certainly does not preclude it. Most of my implementations involve a machine with base/limit registers (before the 68451, etc.), but the techniques are similar. I run two segments (think of it as two LARGE pages), no problem. Unfortunately, time has not permitted sticking in a 68010 and gtrying out veirtual memory operation. To bad, but then...anyone want to consider demand paging off a floppy! [Performance, what's that?]
