I am reposting this because I don't think it got out last week.

I have for sale one (1) Motorola 68851 PMMU (Paged Memory Management Unit).
If you have a Mac with a 68020 CPU and you want to run Version 7.0 or A/UX,
you will need one of these. If you have a 68030 based Mac, the functionality
is built into the CPU.

The number on the lid are:

XC68851RC16A
   1B73S
  DEXX8852

I wondered about the XC (experimental), so I called the local Apple dealer
and had them open up a PMMU box they had. In the number above "8852" is the
manufacture date: 88=1988, 52=week number 52, the 16 means 16 MHz. The PMMU
at the local Apple dealer was older than this one.

The local Apple dealer was selling the PMMU for $425, I'm asking $300 for
mine, I'll pay the shipping. It works now, but if it does not work when you
get, I'll be happy to refund your money.

John
