Interesting. I knew about the 370 card sets; didn't know they were descended
from the 68000. I did work with an IBM 9000 at GE once... really slow, and
the language of choice was Pascal. :-P (fortunately for me, 99% of my work
was on the 11/73 next to it (I was writing a Computer-Aided Instruction
course in MACRO-11 under RT-11/TSX-11)).
