We at PSI are also going towards the Motorola 5100 series, for the same
reason (2300 series non-availability.) We, too, are waiting for the
BSP. And would/will be interested to share the experience.
Up to now we have been using exclusively MVME2306 ioc's which have
served us quite well, thanks to lots of support from the community
(Andrew Johnson & many others.) The problems that we have had have
mostly been due to interrupt handling (which is different from 68K and
not all subroutines for 68K are implemented in the 230x BSP) and some
cross-compiler related issues (alignment, etc.) These are more related
to PPC architecture than the board itself, however. I do not have

any experience with other PPC boards.

At DESY we purchased the 5100-0133 board - since the 2300 series is not
available any more.
Waiting for the vxWorks BSP we got no experience yet.
Would be interesting to share experience with others...

At SNS we are planning to use the MVME2101 for the majority of our IOCs.  We
have one 2112 but Motorola tells us that the 2112 board is being
end-of-lifed.  Since we have not yet bought most of the IOCs, we are looking
at a board in the 5100 family. We have a 5110-2143 board in for eval.  This
board is somewhat more expensive than the 2101 but is also faster, 400MHz
vs. 200MHz. We think, from talking to our rep, that the 2101 will be
Motorola's low end board for at least the time frame that we will be buying
IOC boards.  We are watching the situation day to day as we plan to populate
the crates down the accelerator.

Subject: Re: Recommendations for Power PC VME cards

We are considering an upgrade to our systems to use the Power PC range
of VME CPU cards .  So the  question is  which VME CPU cards do EPICS
users  use?
Which are most compatible with the EPICS software?
thanks for the replies
regards
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).
