I'm guessing that Optima/128 allows 128 meg RAM with the 32-bit clean machines.
For reasons I've never manage to understand, ROM upgrades would be required for
the IIx, cx, and SE/30s out there to use more than 14 or so meg as System
memory.

While the 32 bit memory manager allows a 4 Gig address space, I bet we're only
allocated 1/2 of it.
