-SciSys/Saitek Stratos chesscomputer family (1987-1990)
-(SciSys renamed themselves to Saitek in 1987)
-
-- Stratos
-- Turbo King
-- Corona --> saitek_corona.cpp
-
-IMPORTANT: The user is expected to press the STOP button to turn off the computer.
-When not using -autosave, press that button before exiting MAME, or NVRAM can get corrupt.
-If that happens, the chesscomputer will become unresponsive on next boot. To force a
-cold boot, press ACL, then hold the PLAY button and press GO.
-
-TODO:
-- emulate LCD at lower level, probably an MCU with embedded LCDC
-- LCD status bit handling is guessed. stratos expects it to be high after lcd command 0xf,
- but tking2 won't work if it's done that way, and corona is different too
-- irq timing is derived from the main XTAL, but result should be similar with 5MHz and 5.67MHz,
- there are a couple of "FREQ. SEL" nodes on the PCB, maybe related (not the ones in input ports).
- irq source should be from HELIOS pin 2
-- tking(old revisions) and stratos slow responsive buttons, related to irq timing, but if that's changed,
- the led blinking and in-game clock is too fast
-- does nvram.u7 work? it's cleared during boot, but not used after
-
-===============================================================================
-
-Hardware notes:
-- W65C02 or R65C02 at 5MHz or ~5.6MHz (for latter, box says 6MHz but that's a marketing lie)
-- 2*32KB ROM + optional 32KB Endgame ROM sold separately
-- 8KB RAM + another 8KB RAM(latter not populated on every PCB)
-- NEC gate array for all I/O, Saitek calls it HELIOS
-- side leds are tri-color (red + green, combined = yellow)
-- unknown LCDC under epoxy blob, suspected to be an MCU
-
-Stratos/Turbo King are identical.
-Corona has magnet sensors and two HELIOS chips.
-
-There is no official Saitek program versioning for these. The D/D+ versions are known since
-they're the same chess engine as later Saitek modules, such as the Analyst module.
-Likewise, officially there isn't a "Turbo King II" or "Corona II", these 'sequels' are titled
-as such by the chesscomputer community. Saitek simply advertised them as an improved program.
-
-The initial Stratos/Turbo King (PRG ROM labels known: M,K,L,P) are probably engine version B,
-very few bytes difference between revisions. The first Corona is engine version C.
