ZX Spectrum Cassette Database

In order to maximise the database we need to find as many cassettes as possible, from unknown ones to ones known but we are unable to locate.

If you can help us with any old cassettes you may have in the loft you no longer want or know someone that has then please contact us and give them to a good home, If we can't get there in person we can get them collected by courier - please don't throw them!

Don't worry if you have no old cassettes please register your copy of the emulator by doing so helps us obtain further hardware and software for the project, and plus gives you full functionality of the emulator.
