Summary
12" green monochrome computer monitor from the mid '80s. Like many monitors of its time, it runs at 15 kHz and will accept a standard composite video or luma signal.
Manuals
No documentation is available online at this time.
Notes
As with all monochrome monitors, the picture is much cleaner if you're able to input composite luminance rather than composite video. This can be obtained from S-Video (via an RCA adapter), or from component video if you use the green RCA plug.
