I couldn't find anything webwise.  Do you remember the URL??

OK :)  I found a listing for the 4538 dual monostable multivibrator.  I
still wonder why this circuit uses one -- maybe being not particularly
stable keeps it from locking up or something.

I think I have some 4047 and similar TTL chips in my parts cabinet.  Then
again I'm not sure about a TLE2027, but I'm guessing its just an op-amp.
(If its not in IC Master it will be the subject of my next post :)

Eventually, I'll puzzle out how they get a stable voltage out of this thing
. . .
