Running the large display on the bench

Because the 192 x 64 display makes its own high voltage, it runs from just 5 V and 12 V, even though it is marked for 24 V. A computer power supply drive plug fits its power connector, and the same supply can power a CPU board and display controller at 5 V, enough to run the game in attract mode on the bench.
