You can run VM under system 6 on a mac II using Virtual from Connectix.
Or you can use the Memory CDEV if you're using system 7. On the Mac II,
you need a 68851 PMMU, a memory mgmt. chip (this is built into the
68030 and above.) There used to be bundles of Virtual and a 68851; I
don't know if these bundles are still being sold.
