Clever name, Multiface. An interface that does many things. Also completely untrue: the Multiface wasn’t an interface like a serial interface, which let you plug new kinds of gubbins into your CPC. It just sat on the back of your CPC and did its thing. Singular.
But that was enough. Because the thing in question, for many CPC users, was a godsend. Loading games from tape is tedious: many games were available only on tape, or on disc at an extortionate price: many CPC users had disc drives. Ergo, why not think of an easy way of getting games from tape to disc?
