The Spectrum +3 was designed to load & save to its 3" disk drive, so leads to allow program loading from a cassette player can be hard to come by.
These leads are brand new and allow the connection of a standard tape recorder to the "TAPE/SOUND" socket of the +3.
Also suitable for the new Spectrum NEXT.
Red lead to cassette player MIC socket
White lead to cassette player EAR socket
Software can then be loaded from and saved to tape.
