Doctor QSO & Doctor DX Morse Code Training Cartridges for Commodore 64 with User Manual. I got this with a package of C64-related hardware, and all was in working order, so I don't have a reason to think this won't work. These cartridges have a RCA connector in the back side that look to be used to send audio (have not idea, just guessing). (please look at our rules and privacy policy) |
