Jack...  That sounds perfect!  This isn't high-precision lab stuff, I just
want to get a pretty good idea what the waveforms look like and the p-p
voltage without having my probe significantly alter the circuit operation.
I'm going to order the book right now.  (I've seen it around, and almost
bought it once -- this is a great excuse  ;o)

Thanks!
