I "inherited" a pile of analog and digital chips from an estate "sale" (actually a giveaway) about ten years ago....FINALLY finding the time to sort through them all. Lots of PLLs and 555/566s in the lot and some TTL and CMOS. But the real find is a monolithic function generator-on-a-chip. I'm going to use that for a local oscillator for a vlf receiver. Not sure what I'll do with all the PLLs, but I suppose one can never have too many of those. Stay tuned.
