Richard-

I may have found one at EBAMAN.com. Downloading requires
registration,
which I assume to be free. It looks like 25 Megabytes if
I read the

Thank you very much Fred, this turns out to be it.
While I have an A version it appears to be essentially
identical. The mysterious battery is a 22.5 volt one so I
think a couple of 9 volt batteries in series will work OK.
Its also, of course, useful to know how its supposed to be
used. While individual transistors are considered obsolete
now I still work on quite a bit of gear that has them and
sometimes something more than a DMM is desirable for trouble
shooting them.
