Speaking of front panels, I've always wondered:
In my days with Burroughs systems, the operator consoles that had
"front panels" and many of their maintenance panels used illuminated
momentary push buttons that toggled on/off; that always struck me
as more intuitive (not to mention faster to set up) than separate lights
and switches.
Granted it would require extra logic to latch the states, but was that
kind of front panel ever used on any of the micros and minis that we
discuss here?
