You are correct on CADET. The 1130 was code named SECS for Small Engineerng Computing System. The idea was who could turn down SECS?

I understand 1620 was called CADET, not because it was a beginner
machine, but because it meant "Can't Add, Doesn't Even Try" (the
arithmetic was done with lookup tables, with a little bit of hardware
help for multiply/divide). We had telemetry-processing applications on
1620's that changed the adder table to think in octal.
I understand the 1400 series number came from the original 1400-
character memory size.
Of course, I could be wrong on both scores.
