i do fondly remember the gt-40 and the many hours playing on it.
and i do remember the DEC engineers being bothered about replacing the registers.

gravity...
Eventually DEC Field Circus stopped replacing GT-40 switch registers if
they'd suspected that they were used for playing it :-)
The GT-40 had a primitive loader; it was Craig McGregor of the CSU (UNSW)
who used it to download an 8-bit loader for things like Lunar Lander (I
only wrote a simple "Life" program for it, using the light-pen).
