============================================================================
Skeleton driver, the main issue is to decrypt/identify the main CPU
(something with 0x10-0x40 irq table vectors at the end?).
Skeleton driver, just the main CPU has been identified (a MC68HC11). This one
requires some mods to the cpu core in order to start to work...
Many thanks to Olivier Galibert for the identify effort ;-)
