connects to the Novag Super System Distributor, which can then connect to an
external chessboard, TV interface, computer, etc.
Serial transmission format for Novag Super System is 1 start bit, 8 data bits,
1 stop bit, no parity.

TODO:
- if/when MAME supports an exit callback, hook up power-off switch to that
- add Super System peripherals, each has their own MCU
- serial port isn't working for nsvip v1.x? it only sends empty chars, maybe
there is no problem and the comms protocol is different
- unmapped reads from 0x3* range, same as snova driver
- is (non-super) VIP on the same hardware? minus EPROM or RS232
