But it's not very hard to run code with the ROMs swapped out, and a
small stub handling irqs kernal calls. I managed to get Ultima IV
booting on the Plus/4 this way. If I supply you with the code, could
you add that to the Plus/4 runtime? This way you can use the ram as
real ram.

Marko Mäkelä's 256 kB expansion. There are similar hacks for the
Plus/4.
