I also received a PMMU (16MHz) --- thanks^2!  After realizing what was
involved in the installation (I have an 18-month old Mac II), I decided
to let the on-campus microcomputer people put in the PMMU.  (I readily
admit to being a klutz.)  They said that the installation would be done
quickly and that the charge would be nominal.

They phoned me later with the unfortunate news that the PMMU was
failing the diagnostic program which they had received from Apple.  I
infer that the problem was somewhat subtle (conceivably non-existent)
and that MacEnvy would have reported the existence of the PMMU.  These
on-campus people are an "authorized Apple dealer" and apparently spent
a fair amount of time on the phone with Apple verifying that the PMMU
was irregular and that there was nothing wrong with my logic board.
They will return my Mac II with the PMMU in a separate box, and I will
try to swap the PMMU with Motorola.

Since most people with PMMUs are currently not giving them a workout,
it would be useful to have a program which checked that a PMMU is
flawless and correctly installed.  The person I spoke with on campus
claimed that he was absolutely forbidden by Apple to give me a copy of
the application that he ran.  The obvious solution would be for Apple
to release whatever program was run on my machine.
