I'd like to build some type of device to take the signal from the RF out (Analog TV Channel 2-3) on some of my 8-bit computers and split out the audio and video signal for use on HDMI or VGA+Audio. I know there are devices/TVs can still tune Analog but they generally have a hard time staying tuned into the signals these antiques produce. With some exceptions LCD and other tuners constantly try to auto-tune w/o ever locking.
Of course there are mods that can be done inside the computers to get composite video but I don't want to modify these increasingly rare machines. Not to mention getting Audio often involves even more mods.
I've got experience w/Arduino and ESP32 microcontrollers and basic electronics. I'm in the early stages of tackling FPGA's but I'm thinking this might be a good project learn with. I do have FPGA Dev boards with VGA and HDMI outputs on them already.
My assumption is I may be able to put together some type of Analog circuit to capture the signal and connect that to a FPGA for processing to get output in VGA or possibly HDMI. Does anyone have some ideas on where to start or how something like this could be made to work?
