Re: What does PMMU mean, anyway? It is simply impossible that Tenchusatsu hasn't heard of a paged memory management unit. Who are you and why are you posting from his account? :-) The Macintosh II was a 68020 based machine running at 16 MHz RAM was 1 MB - 20 MB using standard 30-pin SIMMs, had an optional PMMU, and standard FPU. Hard disk was 20 MB - 80 MB, and floppy drive was 800K (dual 800K was optional). It was not 32-bit clean. Later Apple offered an upgrade for the 1.44 MB Superdrive for the Mac II. This changed the ROMs, added a PMMU (Paged Memory Management Unit - for virtual memory use), and 1.44 MB floppy drive(s), and made the machine 32-bit clean. acornworld.net
