-AVR-Max Chess Computer, aka "SHAH"
-In Germany it was named AVR-Max-Schachzwerg
-
-The chess engine is H.G. Muller's micro-Max 4.8, ATMega88 port and prototype
-hardware design by Andre Adrian. PCB finalization by Elektor, published in
-Elektor magazine in 2009.
-
-FN 1 = new game, FN 2 = set level, FN 3 = principle variation.
-Moves are confirmed by pressing GO twice.
-
-Hardware notes:
-- PCB label 081101-1 (c)Elektor v1.4
-- Atmel ATMega88P-20PU @ ~8MHz, 8KB internal ROM
-- 4-digit 7seg display, button panel, no sound
-
-TODO:
-- AVR8 SLEEP opcode is not working, it's used for power-saving here and was
- harmless to hack out, but needs to be put back when it's emulated
-- add Elektor CC2 version with custom LCD screen
