TeleVideo TV-910 / 910 Plus

Preliminary driver by R. Belmont

Hardware:

6502 CPU

6545 CRTC

6551 ACIA

IRQ = ACIA wire-OR CRTC VBlank

NMI = AY-5-3600 keyboard char present

TODO:
|

- Character attributes: how is that even possible? (Esc-V brings up test screen)
|
||||
- DIP switches don't all appear to have the expected effects
|

- Keyboard hookup isn't quite right
