-Дебют / Дебют-М (Debut) Chess Computer
-
-Released in 1994 in Russian Federation by ЭНЕРГОПРИБОР (Energopribor), Moscow.
-It's running the Mirage chess engine by Vladimir Rybinkin, originally made for MS-DOS.
-
-TODO:
-- where does the interrupt come from?
-- Debut-M is an updated version? Or is it the same program as Debut with a redesigned case?
-

-Hardware notes:
-- КР1810ВМ86 (i8086 clone), 16200K XTAL
-- КР1810ГФ84 (i8284 clock divider /3)
-- 2*КР537РУ10 (2KB*8 RAM), 2*КС573РФ4А or similar (8KB ROM)
-- lcd panel (4 7seg digits), 64 chessboard buttons, 16 leds
-
-A bit more detailed, list of other Soviet standard TTL chips used and their equivalents:
-- 2*КР580ИР82 = Intel 8282, aka 74573
-- 2*К555ЛЛ1 = 7432
-- К555ИЛ7 = 74138
-- К555ИД10В = 74145
-- КМ555КЛ15 = 74251
-- К561ЛЕ5А = CD4001
-- PC74HC259P = the odd one out

-keypad legend:
-
-АН - анализ (analysis, switches view info)
-ХОД - ходи (force move)
-ИНТ - интерактивность (interactivity, switches 1P vs CPU, or 2P)
-ПОЗ - позиция (position mode)
-ВФ - выбор фигуры (select piece)
-ВП - возврат (take back 2 plies)
-УР - уровень игры (level)
-ВВ - ввод позиции (enter position)
-СБ - сброс / новая игра (reset / new game)
