I recently got some parts from work and I was sorting them, turns out there were like 40 MPSA70's in there. I also got a bunch of cd4046 ics, as well as some ca3086 and ca3030.
I honestly just don't know what to do with them I know the 70's are a complementary npn/pnp darlington transistor for use as a general amplifier, and I know that some of the chips are pll's with vco's on board but I just wouldn't begin to know what to do with them, Maybe a phaser or something?
Any ideas and suggestions are welcome!

MPSA70 is a loose-spec PNP (not a complementary Darlington).

Generally useful as a jellybean PNP.
