video output. Method of output is through a DG640 board (sold by

Applied Technology) which uses a MCM6574 as a character generator.

The DG640 also supports blinking, reverse-video, and LORES graphics.

It is a S100 card.

It is a S100 card, also known as ETI-640.

Keyboard input, like PIPBUG, is via a serial device.

real hardware. But you can save, and load it back.
