Tandy Color Computer 3- Couple questions in Tandy Computers Posted June 26, 2014 .I do know it has composite & like I said, I am counting on that to work, but what I was really wanting to know is if there were any higher quality options involving the RGB out to an HDMI port on my TV or something...Im guessing I could do the RGB to VGA cable & run that to a VGA to HDMI upscaler if no such thing as a RGB to HDMI exists.... I recently bought a Commodore monitor and cables from cloud9 for the Coco3. Surprisingly my newish 27inch Asus monitor displays the Coco3 perfectly with only the cloud9 RGB to VGA cable. ....and as discussed above, I can't recommend cloud9 enough. I recently got a twin disk drive system as apparently some software only works when that hardware is present. I'm glad I forked out for the drives and controller, something satisfying about hearing the drive tick away loading software!
