Came across a Radio Shack 26-1201 TRS-80 video display at an antique mall for $20 yesterday - allegedly it works, but I do not have a TRS-80 to try it out with. I have read you can connect a TRS-80 to a composite display by making a simple DIN-5 to composite adapter and only hooking up pins 4 & 5.

Would that work the other way around? My understanding is that at least one of the 5 pins is 5v, so I assume the monitor needs that for some reason.

@prokyonid I suspect so. The TRS-80 monitor works just fine on a CoCo as well. Hilarious.

@seanwbruno I have no CoCo either - my Tandys are all x86-based.

@prokyonid The 5V pin is used to power an RF modulator box when hooking up to a regular TV. The TRS-80 monitor was an RCA TV that had been nodded to have a composite input. It should be fine with any composite video source AFAIK.

@prokyonid the original monitor was a cheap RCA portable television they pulled the tuner out of.
