I propose a little contest, for all you hardware freaks out there.  Suppose we
just sit down, and try and recall/imagine what the beasties are.  Post your
answers, and then go look them up.  I will tally the best guesses/answers,
and reward the winner with a suitable Negotiable Prize.  No "skill testing"
for this one.

My contributions?  Lessee-  74117, 74118- some sort of drivers, I think for
high speed lines. The 2106/2107 are OOOOLLLLLD MOS rams, and should be classed
as "antiques".  Save these, and crack them open, and put them on display
next to a current 64K ram...  2111 and 2115 I think are rams also.

MC14495 is a CMOS gate, uuhhh, I think it just might be a phase locked loop.
Is the 74119 an 8x8 RAM?
