However, I believe I have read somewhere that a simple plug-it-in PMMU will not be possible on the LC, because of the way it was built. I'm not a technician, and I don't remember all of the details, but there was something like the PMMU has to sit between the CPU and the memory, which is not possible when plugging things into a processor-direct clot. Er, slot, that is. Like I said, I'm not a technician, so I could be wrong on this. It wouldn't be the first time :-) Erik 6500erik@ucsbuxa.ucsb.edu or 6500erik@ucsbuxa.BITNET "Graduate school is for the birds!"
