That would actually be MIPS processors. The MIPS architecture came out of
Stanford and stands for (supposedly) "Microprocessor without Interlocking
Pipeline Stages".

Yup.

Usually called a PIC (peripheral interface controller).

Let me know if you ever want to get rid of those...I have several complete
chipsets, but can always use spares.

Well...it was the standard a decade or two ago; the standard came out around
1980, AFAIK. I don't think that there has been a hard requirement for 1750A
in military contracts for a long, long time. It's only a 16-bit processor,
after all, and almost noone makes it any more (Performance doesn't). It,
like the JOVIAL programming language often used to program it, are probably
only around for maintenance and upgrades of existing platforms.
