/*******************************************************************************
Mephisto Academy
Hardware notes:
- PCB label HGS 10 130 01
- VL65NC02-04PC @ 4.91MHz
- 2*32KB ROM(TC57256AD-12), 1st ROM half-unused (A14 = VCC)
- 8KB battery-backed RAM(TC5564APL-15)
- HD44100H, HD44780, 2*16 chars LCD screen
- 8 tri-color leds (not fully used: always outputs 6 red, 2 green)
- magnets chessboard with leds, piezo
Since the program is on an external module, it appears it was meant to be
a modular chesscomputer. However, no extra modules were sold separately.
Module PCB is the same as Super Mondial II College, label HGS 10 116 05.
The T+T version is (presumably the first version of) Polgar ported over to
Academy hardware. Much unused data remains, and the TRAIN button doesn't work.
