I remember something like that. All the logic was in a control box, connected
to the displays by forearm-diameter (well, maybe half) cables. If I inserted
enough
characters at the front of a 900-character string it got slower and slower;
finally
the controller crashed and automatically rebooted.

We had a line printer (Documation) on which we kept a T-11 band It was about
40%
busy. But during the that 40%, the clackity-clack was the tongues of assembler
programmers bemoaning how much slower their hexadecimal reports printed than
if we had kept a P-11 band mounted. Old biases die hard.
