Multiface

The Multiface was a hardware peripheral released by Romantic Robot UK Ltd. for several 1980s home computers. The primary function of the device was to dump the computer's memory to external storage, and it featured an iconic 'red button' that could be pressed at any time in order to activate it. As most games of the era did not have a save game feature, the Multiface allowed players to save their position by saving a loadable snapshot of the game. However, this same snapshot feature also allowed users to create backups or unauthorized copies of software. Copyright infringement was discouraged, yet possible in earlier models, but was made more difficult in later models by requiring the Multiface to be present when re-loading the dumps into memory.

Multifaces were released for 8-bit and 16-bit microcomputers, such as the ZX Spectrum, Amstrad CPC & Atari ST. Different models had slightly different features.

The Multiface One was released in 1986 for the ZX Spectrum 48K. It cost £29.95 and had the capability of saving data to cassette tape, ZX Microdrive, Opus Discovery (an external 3.5 inch disk drive) or Technology Research Beta (an interface that allowed 5.25 inch and 3.5 inch drives to be connected). The device worked on 128K Spectrums, but only if they were put in 48K mode. It featured a Kempston joystick port, and later revisions contained a switch that effectively 'hid' the device from software. Early versions had a composite video out port but this feature was later removed.
