[comp.sys.mac] 68851 PMMU part number

Okey dokey. I bought a 68851 PMMU for $190 tonight at the BMUG
meeting. Problem: It's part number is XC68851R16.

The part number most people refer to is RC16, and is MC, and not
XC. As I understand Motorola's numbering, the XC denotes that
this is not a final production chip, but I have no idea what
the R vs RC is. Should I return this and get in on a group buy?

Any known bugs in this chip that will cause any problems in the
future?
