Description

Tandy TRS-80 Video Mixer Composite Out

This composite video mixer board combines the video signals of a TRS-80 Model II, III, 4 or 4P computer into a monochrome composite video signal.

A very handy tool to have if you often work on those types of computers! You can just put aside that big annoying CRT top part of the computer's case that always seems to be in the way while working, and just use another monitor with a composite video cable.

Important note:

This solution is not compatible with all monitors! Please see the manual for which monitors have been tested to work.
