I haven't been around in many moons! Hopefully no-one will hold that against me! My question seems relatively easy, but as is usually the case, nothing is as simple as it seems! I have two old homebrews that I built 2 or 3 yrs ago. They both use the Radio shack 49-925 sensor with Canon Owls cameras. Is there a way to replace only the cameras with digitals, or would I have to replace the sensors also?
