- First of all, the correct spelling for the card is PMMU, which stands for
- Paged Memory Management Unit. With this hardware addition, you can use
- virtual memory.
-
- Second of all, it's not required for the LCII to address 10MB of RAM. You
- can go ahead and install those 4 meg simms, today! :)
-
- Lastly, because the LCII is based on a 68030 processor with a PMMU built-in,
- virtual memory is available to you anyway when those 10MB of RAM dwindle away.
