I can't get many older orcs to work with the most recent perf3.47 on the Mac.
How do I revert to using an older version of perf?

There have been comments that people didn't understand the need for the
physically modelled opcodes, but they are exactly what have been waiting for,
so many thanks to those responsible for including them.

	better yet - post the orc/sco to the list for others to verify
bugs and then squash them....
