/*******************************************************************************
Skeleton driver for Merit Scorpion DX darts machines
Hardware overview:
Main CPU: AMD Elan SC300-33KC (Am386SXLV CPU core + 6845 CGA)
Others: Dallas 1232, M48T08-150PC1, F82C735A, PCMCIA slot (for a modem),
LCD CGA screen and magnetic stripe card reader
OSC: 24.000 MHz
Notes:
Uses a ROM-DOS as its operating system.
The card reader emulates a PS2 keyboard. The keyboard BIOS is undumped
(it's a Phoenix BIOS on a protected Intel 8242 MCU).
The Flash ROMs contain user data (from a championship on Spain). Once emulated,
they must be reflashed with a factory reset (can be done on the emulated
system) and updated on the driver.
