In a recent post, the price of a PMMU was given as $490, with
the additional comment that dealer installation was required.

At work, we've got about 60 Mac II's, all with PMMU chips in them.
As far as I know, they are utterly useless unless you're running
A/UX, in which case they are necessary.  (Don't ask why we got them;
we're Carnegie Mellon, we don't have to have a reason.)  In any event,
no miracle occurs when you plug a PMMU in; you need software to get
it to do anything, and System 6.0 doesn't have any code to use it.
(This isn't technical knowledge, just experience; I've used Mac II's
with and without, and couldn't tell the difference.)
Also, dealer installation is required simply to make sure dealer profit
margins stay good.  Basically, all that's needed is a chip puller (or
a screwdriver and some caution) to do the installation.  Takes about
10 minutes from start to finish.  So if you can find a PMMU without
going through Apple, don't worry about the installation
