The keyboard controller is one of those custom XR devices.
Will use the terminal keyboard instead.
With bios 1, after entering your userid and password, you get a black
screen. This is normal, because it joins to a network which isn't there.
ToDo:
- Almost Everything!
- Connect up the device ports & lines
- Find out about graphics mode and how it is selected
- There is a beeper or speaker connected to the 6840 - how?
- Fix Keyboard so that the Enter key tells BASIC to do something
- Fix If ^G is pressed, emulation freezes
- Fix If ^G is pressed, the system pauses for about 30 seconds.
- Find out how to make 2nd teletext screen to display
