I've found lots of crystals and TTL oscillator types from old 286/386/486
motherboards - that sold at auction for $2 to $10 each. Also speak to some
of the repair companies - they throw a whole board out and can't be bothered
desoldering the crystals.

I've now got a collection of about 100 or so TTL oscillators from 8Mhz to
80Mhz with all sorts of unusual values in-between. SOme at 36Mhz which are
great if you are into overclocking a 33Mhz PC, these came from old HP-IB
equipment and a HP1000 interface board - the whole cabinet was $20 at auction.

Some more electrons resulting in matter...

Some say there is no magic but, all things begin with thought then it becomes
academic, then some poor slob works out a practical way to implement all that
theory, this is called Engineering - for most people another form of magic.
