Pinouts for a Nanao CRT model MG-550CDM? - test-drb@ccmp.vtda.org

14 Jul 2006

I have a small (5"?) panel-mount CRT here I'm trying to fire up.  The
label on the top suggests that it's made by Nanao and is a model
MG-550CDM.  Google turned up a hit or two, but no real information.
The PCB has a 10-pin single-sided edge-connector, visually similar to
the style Commodore used on PETs and C-64s.  There are two connectors
on the back of the chassis - an RCA, clearly NTSC video in, and a 2x3
molex connector, obviously power and perhaps some additional control.
This came out of some piece of radio comms gear, if that helps place
its context.

...
 From what I can tell from cursory inspection, pins 1
and 10 are ground, 5 and 9 appear to be no connect, 8 is NTSC in, 7 seems to be
AC in (can't identify AC return...), and 2, 3, 4, and 6 disappear into
the bowels of the circuitry.

If I'm lucky, there is some sort of industry convention in play here.
Does this arrangement ring any bells with anyone?

Thanks,
