Atari 1020 - FujiNetWIFI/fujinet-firmware GitHub Wiki

Atari licensed a small plotter from ALPS, and produced the 1020 from 1983 until 1985. The 1020 had four colored pens: black, red, blue, and green, which could be individually used to draw calligraphic shapes onto the paper.

Its design was similar to the Atari 1010 cassette recorder.

The printer itself had a font in ROM which the printer could draw with its pens to output text, albeit very slowly.

The FujiNet implementation outputs to SVG, and is currently missing the font for accurate text output, but is otherwise completely implemented.
