Speccy Tape is a simple utility that converts your device into cassette player for ZX Spectrum computer. It simply plays out the TZX and TAP files via the speaker/jack.
Please not that in order to feed the signal to ZX you need to amplify it. It works perfectly if you are using a tape player ( or ZX +2 ) and the car cassette adapter.
Connect the device to the Spectrum put your files via iTunes/Mail or Safari and enjoy.
The application contains my 20+years old demo I've made.
