I have an Italian made CRT made by Seleco (SMV-290) that I purchased for an arcade project years ago. I want to use it for retro gaming today, but I'm not sure about the connections. I connected a SNES via SCART and switched things around until I got at BEAUTIFUL picture! I'm hoping to find anything that might help with understanding the switches, pinout of the DB9, and maybe even a schematic of the board to help with cap replacement on the PSU section. I found an instagram post from January or so of someone who's set one up, so I know there are at least a couple people out there that might know something.
