- rebel5 unknown read from 0x4002, looks like leftover bookrom check
- need to emulate TurboKit properly, also for mm5p (it's not as simple as a CPU
  overclock plus ROM patch)

Mephisto 4 Turbo Kit 18mhz - (mm4tk)
    This is a replacement rom combining the turbo kit initial rom with the original MM IV.
    The Turbo Kit powers up to it's tiny rom, copies itself to ram, banks in normal rom,
    copies that to faster SRAM, then patches the checksum and the LED blink delays.
    If someone else wants to code up the power up banking, feel free

    There is an undumped MM V Turbo Kit, which will be the exact same except for location of
    the patches. The mm5tk just needs the normal mm5 ROM swapped out for that one to
    blinks the LEDs a little slower.

    -- Cowering (2011)

The MM V prototype was the program that Ed Schroeder participated with as "Rebel" at the
1989 WMCCC in Portorose. It was used with the TK20 TurboKit.
For more information, see: http://chesseval.com/ChessEvalJournal/PrototypeMMV.htm

MM VI (Saitek, 1994) is on different hardware, H8 CPU.
