Not really... but they were called the "Computer Chess Reports test positions"
and were often named as CCR-1, then CCR-2 for a second revision, etc.  I don't
know exactly how many he did, perhaps Don is around and might remember.  I think
I tried at least three different ones however.  If any of the old CCR's are in
the web archive, they ought to be there.  And they might be on any ftp site that
carries test suites...
