You need the PMMU chip (MC 68851) for the Mac II to be able to use VM.
68030+ chips have the PMMU built-in, so they have VM "instantly" ;-)

This chip is on Apple's price list.

Connectix released MODE32, which enables 32-bit memory addressing on non-
32-bit clean (pre-IIci) machines.  This product has been bought and is being
distributed freely by Apple.  It allows you to have more than 8MB of "real"
RAM in your machine.
