I've never worked with MIPS, but I used to work a lot with Data General
Nova & Eclipse machine language.  It had some curious instructions.  I
even worked down at the microcode level on the Eclipes, which can be
really *FUN*.  :-)

I also used to work a lot with the Intel 8080 machine code on my Imsai
8080 and also some exposure to 6502 & 6809 in my courses at Ryerson.  It
can be an interesting area to work in, where you have direct control
over the CPU.

BTW, I also found a bug in the National Semiconductor 8250 UART, which
was originally used in the PC.  I reported it to them, but I have no
idea if they fixed it, as I developed a work around.  This was on an 8
port serial port board I designed & built for my Imsai.
