[ snipped unrelated info ]
Since it is relatively easy to equip a IIgs with 4MB (or more) of
directly addressable memory, I don't think that much swapping would
be needed.  (Nor would it be very fast, at a peak transfer rate of
1MB/second.)




Sorry Mike, but only 4 MB is directly accessible.
To get to 8MB or more, that 4MB is banked and switched
by accessing the ROM memory manager. Hence all of the
extra logic on the OctoRAM and Sirius ram cards, which
by the way, the Sirius is a direct copy of the OctoRAM.


Interesting.

I was under the impression that 8MB of the address space was
devoted to RAM and 8MB to ROM.
