I worked on the 1620, which would tell you how it was doing by
placing an AM radio on top...  No need for wires, since the current
switching in the core memory gerenated enough RF noise.  NOP was
180 microseconds, so a FORTRAN do loop with one SIN computation
was very slow: blink blink on the lights, and click click on the radio.

As for RF noise, if you programmed timed loops, you could generate
music.
