Sinclair ZX80 / ZX81 / Z88 Forums

I'm trying to figure out how to load ZX80 software from a TZXduino. My ZX80 works perfectly, including Paul Farrow's Kong and Pacman tape via cassette player, plus small basic stuff i can save and load. I can't seem to figure out how to get the .o files from the player to the machine. It say 'playing' but no % counter or signal to ZX80.

Any help would be appreciated. Plus I know I posted in hardware thread.

Did you try to clean the connectors or verify that a signal is present on the PCB? I had an intermittent power connector and after replacing it, it was fine. For a first try I use DeOxit contact cleaner. Also verify that the cables are working.
