So far, Vern takes the award for the earliest ICs :-)

It's great to see the replies already! I am probably one of the youngest
listmembers (born in 1980) but this old stuff really fascinates me. I got
my stock of "old chips" from a copier repair facility that was clearing out
its old stock. There was some _really_ old stuff in there, including nixie
tubes. It is interesting to see some of the technology that was used in
these copiers, office calculators, etc. Occasionally I use some of these
old ICs. It is interesting to see a breadboard with a PIC next to a 7400
from 1971!

I have several boards from them with ICs on them which have FOUR rows of
pins. They are like a plastic DIP package except that the row of pins
coming out each side splits into an outer and an inner row of vertical
pins. I have all this stuff back at my parents' house so I can't look at
the numbers on them now, but any idea what that package was called and in
what date range it was used? Must have been fairly late as these boards
look highly integrated (looks like a CPU, RAM, and ROM), so my guess would
be late seventies but I'm unsure.
