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.
IIRC Norbits were a Philips idea - blocks of epoxy in various colours
depending on the implemented logical function - which was implemented
internally with discretes. Aimed at the market that uses PLCs these
days - a good idea at the time, but not widely used.
