Want to get even more obscure? I worked on some machinery a while back (QUITE
a while back :-) that used some logic parts made by Amperex that they called
"Norbits" -- these things were HUGE compared to normal DIPs and all of them
had an odd number of pins, typically 17 though some had other numbers. I
might even still have some data on those around someplace.

I can still find 74h, 74F, 74S, 74hct, 74c, 74hc
nevermining what I
have on hand.
It was interesting, useful and a PAIN. It sometimes made a huge differnce
if you subbed a S04 where there was an LS04.
Stiill 74xx family of stuff! Well almost now that CMOS has taken over,
we have a whole lot of custom tristate buffers and latches but not much
more. Where do you find High Threshold Logic for Industrial Applications.
What about your aging aircraft like the SST that used 70's componernts?
