Dennis,

  The Fermilab D0 experiment successfully uses MVME2301, MVME2304, and
MVME2604 processor boards -- we have ~100 PPC processors in the D0
control system. Depending upon your application, there may be other
MVME-series PPC boards that would better suit your purposes (i.e. a
better performance/price ratio). Keep in mind that these boards can
not be field-upgraded to add memory; so, when you estimate your memory
requirements, allow for sufficient expansion -- EPICS data structures
tend to be large.  I usually purchase boards with at least twice the
memory that I estimate will be initially required.

  We also have MVME162 processors (M68K family) and the same C and C++
source code builds for both processor families (with one or two
conditional sections).
