RGBench Now Available from CastleMania Games

CastleMania Games is now selling qwertymodo’s ‘RGBench’:  A device designed to make it easy to connect component video, SCART and VGA, directly into an oscilloscope, without constantly changing cables:  https://retrorgb.link/rgbench I’ve personally tested this device and have found it to work very well for testing video voltages.  It’s switchable 75ohm termination means it’ll work well both […]

Building A Passive Sync Combiner

There are many scenarios in the retro gaming world that you might need to use “VGA”, or RGBHV on a device that only accepts RGBs.  I think the most common scenario might be people connecting 640×480 VGA to a 480p compatible RGB monitor, but there’s quite a few others, depending on your setup.
