[Coco] CM-8 Monitor Manual

I recently acquired a CM-8 monitor from eBay and it doesn’t power up – no power LED, no raster, no power to the filament tube. I don’t have access to a high voltage anode probe.


I checked for the obvious failures (fuses, power switch, burn components) but no luck.


I need to find a repair (not owners) manual. Otherwise, I will have to reverse engineer this thing.


Didn’t see one in the CoCo archives.



Thanks in advance
