-Fidelity Sensory Chess Challenger "9" (SC9) overview:
-- 8*(8+1) buttons, 8*8+1 LEDs
-- 36-pin edge connector, assume same as SC12
-- 2KB RAM(TMM2016P), 2*8KB ROM(HN48364P)
-- R6502-13, 1.4MHz from resonator, another pcb with the same resonator was measured 1.49MHz*
-- PCB label 510-1046C01 2-1-82
-
-*: 2 other boards were measured 1.60MHz and 1.88MHz(newest serial). Online references
-suggest 3 versions of SC9(C01) total: 1.5MHz, 1.6MHz, and 1.9MHz.
-
-I/O is via TTL, not further documented here
-
-3 versions were available, the newest "B" version was 2MHz and included the Budapest program.
-The Playmatic S was only released in Germany, it's basically a 'deluxe' version of SC9
-with magnet sensors and came with CB9 and CB16.
-
-Starting with SC9, Fidelity added a cartridge slot to their chess computers, meant for
-extra book opening databases and recorded games.
-
-Known modules (*denotes undumped):
-- CB9: Challenger Book Openings 1 - 8KB (label not known)
-- CB16: Challenger Book Openings 2 - 8+8KB 101-1042A01,02
-- *CG64: 64 Greatest Games
-- *EOA-EOE: Challenger Book Openings: Chess Encyclopedia Volume A-E (5 modules)
-- *TDF: Challenger Book Openings: Tarrasch Defense to the Queen's Gambit
-
-The edge connector has D0-D7, A0-A13, 2 chip select lines, read/write lines, IRQ line.
-IRQ and write strobe are unused. Maximum known size is 16KB.
