   What procedure is followed to install a 68851 PMMU into a Mac II?
   Just drop the chip in?  What orientation?  I assume with the lettering
   facing the same way as all the others?

First you have to pull out the pseudo-mmu.  When you put in the 68851, there
is a notch in one corner of the socket which matches a notch or gold line
on one corner of the top of the chip.

Be careful not to bend any pins.  And of course, the customary static
precautions apply.
