-Mephisto Polgar and RISC
+Mephisto Polgar
-The chess engine in Mephisto Risc is also compatible with Tasc's The ChessMachine.
+Hardware notes:
+- RP65C02G @ 4.91MHz
+- 64KB ROM
+- Mephisto modular display module
+- Mephisto Exclusive/Muenchen chessboard
-TODO:
-- split driver into several files? mrisc for example is completely different hw
-
-**************************************************************************************************/
+The 10MHz version has a W65C02P-8 @ 9.83MHz.
