A addon from [[Draysoft]] & [[Evesham Micro Centre]] that enables you to make doublicates of tapes and copy software. The device connects to expansion port, and allows to copy data from an external tape deck to the CPC464's built-in tape recorder.
Draysoft & Evesham Micro Centre also produced a Doubler version for the [[ZX Spectrum]]. According to adverts, using the same concept, but in opposite direction (ZX version outputs to recording deck, whilst CPC version inputs from playback deck)doubler also had "spectacular success on the CBM64".
