The video controller displayed 24 lines by 40 columns of monochrome, upper-case-only (the original character set matches ASCII characters 20h to 5Fh) text on the screen, with NTSC composite video output suitable for display on a TV monitor, or on a regular TV set by way of a separate RF modulator.
Composite video output was provided for an external monitor, and an internal RF modulator provided a separate output to drive a television set.
