TK-80BS (c) 1980 NEC
Preliminary driver by Angelo Salese
Various additions by Robbbert
The TK80BS (Basic Station) has a plugin keyboard, BASIC in rom,
and connected to a tv.
TODO:
- (try to) dump proper roms, the whole driver is based off fake roms;
- BASIC doesn't seem to work properly; (It does if you type NEW first)
- bios 0 BASIC doesn't seem to work properly; (It does if you type NEW first)
- bios 1 does not boot up because it runs off into the weeds
- bios 2 also does that, somehow it starts up anyway, but no commands work
