A MMU is short for Memory Managment Unit. It was a seperate chip on my
Commodore 020 board but is built into the 030 chip on my GVP combo board.
(I've since heard that there are some economy 030's that don't have it)
What it does is lets you do certain tricks with your memory. By using a
program like SetCPU you can copy KickStart into 32 bit memory and then have
the MMU have the operating system look there for it instead of in ROM.
This really speeds things up. The program Enforcer uses the MMU to do its
tricks also and will decline to run an a machine without one.
