* TODO:
* - dump CROM and emulate cpu at microinstruction level
* - memory modes with IOCNT0, currently ignored
* - memory modes with IOCNT0, currently always running in full expansion mode
* - timer event counter mode (timer control register, bit 6)
* - TMS70x1/2 serial port and timer 3
* - when they're needed, add TMS70Cx2, TMS7742, TMS77C82, SE70xxx

TODO:
- some strange bugs with cartridge software, maybe TMS7000 bug?
- some strange bugs with Games I cartridge, bad dump or emulation bug?
- other RAM configurations (6KB(default), 12KB, 18KB, external)
- Hexbus interface and peripherals
- HD44100 is not accessed by the CPU, is it connected to the HD44780?
