- These I think I remember. If the switch is in the "6502" position, the
- machine boots up into BASIC 4.0 and acts like an 8096. If you put it in the
- "6809" position then the Waterloo system boots up and it acts like a MicroWAT.
- If you put it in "Prog" then you can switch back and forth, likely through a
- kind of "Switcheroo Pivot" thing.
