The board came out in 1977. It was very useful and well recieved.


The MIO, Multiple Input Output Board, was designed to meet all Input/Output requirements of most 8080 System users by pro­viding the User with the following Input/ Output interfaces:
A Data Storage interface to a standard audio cassette recorder;
Two Parallel Input/Output (PIO) ports;
One  Serial Input/Output port; and
One control port to be used for internal and external control functions.

As an example of its versatility, a single MIO Board could control a TV Typewriter, a Line Printer, a Teletype, and a cassette recorder
The manual for this board can be obtained here and here.
