Jameco, also; I've gotten quite a few older ICs to

the wrong places) from them. CMOS ICs are in a slightly different
class, but he might be able to get better than scrap for them. I've
very little use for them myself.
Don't a lot of 4000-series ICs have 74HCxxxx equivalents? I've still
got a bunch of old 4000-series CMOS from when they first started
appearing. ISTR that they were very slow, unless one used high
(+15V?) supplies. I think I still have my Solid State Scientific
databook from that time.
