I know this is the wrong place to post this but I can't find any Timex-Sinclair computer newsgroups (like there would be). I have a Sinclair ZX80 which I'm trying to get to work. I have it hooked up via RF modulator to a TV, and have a 9V adaptor plugged in; it's not giving my a display although I know it's on because when I hook earphones to it I get a low buzz. Any ideas?
