There are currently five BASIC-DOS demo configurations:

  1. Single 25x80 session
  2. Two 40-column sessions
  3. Two 80-column sessions
  4. Dual monitors with single sessions
  5. Dual monitors with multiple sessions

The 40 and 80-column demos are configured with borders. A double-wide border indicates which session has keyboard focus. Use SHIFT-TAB to toggle focus.

BASIC-DOS development was performed on this PC XT Build Machine. It’s also available with Dual Monitors.
