-Fidelity Sensory Chess Challenger 6 (model SC6)
-Fidelity Mini Sensory Chess Challenger (model MSC, 1982 version)
-Fidelity The Gambit (model 6084)
-
-TODO:
-- MSC MCU is currently emulated as I8039, due to missing EA pin emulation
-- different button panel for fidel_msc_v2 artwork
-- add the older versions of gambit(assuming different ROM): 1st version is
- probably the same as "The Classic", and 2nd version has voice capability
-
--------------------------------------------------------------------------------
-
-SC6 hardware notes:
-- PCB label 510-1045B01
-- INS8040N-11 MCU, 11MHz XTAL
-- external 4KB ROM 2332 101-1035A01, in module slot
-- buzzer, 2 7seg LEDs, 8*8 chessboard buttons
-
-SC6 released modules, * denotes not dumped yet:
-- *BO6: Book Openings I
-- *CG6: Greatest Chess Games 1
-- SC6: pack-in, original program
-
-SC6 program is contained in BO6 and CG6.
-
--------------------------------------------------------------------------------
-
-MSC hardware notes:
-- PCB label 510-1044B01
-- P8049H MCU, 2KB internal ROM, 11MHz XTAL
-- buzzer, 18 leds, 8*8 chessboard buttons, module slot
-
-MCU ports I/O is identical to SC6.
-
-It accepts the same modules as the 1st MSC version. See fidel_msc.cpp for known
-modules. The module overrides the internal ROM, by asserting the EA pin.
-
--------------------------------------------------------------------------------
-
-Gambit(v3) hardware notes:
-- PCB label 510-1115A01 (1986 PCB, but chips from 1989)
-- TMP80C50AP-6-9311 MCU, 4KB internal ROM, 6MHz XTAL
-- buzzer, 16 leds, 8*8 chessboard buttons
-
-MCU ports I/O again identical to SC6.
-The same MCU+ROM was also used in Designer 1500(PCB label 510.1131A01).
-
-Gambit Voice hardware notes:
-- TMP80C50AP-6-9311 MCU, 4KB internal ROM, 6MHz XTAL
-- 510.1117A01 sound PCB, the one from Excel Voice, but with 2332 ROM
-- speaker, 16 leds, 8*8 chessboard buttons
-
-Silver Bullet hardware notes:
-- PCB from MSC, but lose/check leds unpopulated
-- TMP80C50AP-6-9311 MCU, 4KB internal ROM, 6MHz XTAL
-- buzzer, 16 leds, 8*8 chessboard buttons, module slot
-
-To summarize, known MCU chip ROM serials+year:
-- 100-1020B01 (1989), The Gambit
-- 100-1020B02 (1986), Silver Bullet
-- 100-1020B02 (1987), The Classic
-- 100-1020C01 (1987), Gambit Voice
