Port Expander for the Atari 400 and 800 Computers - Dismantled for reference and curiosity

Atari 850 Rev 7

The Atari 850 is a port expander which includes four RS-232 ports and one Centronics parallel port.

It was marketed for use with the Atari 400 and 800 and yet in truth it could be used with pretty much any 8-Bit Atari microcomputer.

It is exceptionally boring visually, however to its credit it works surprisingly well.
