This ZX81 has been placed inside a kit case which does not have a manufacturers mark. If anyone can help identify it, then please let us know.

It has a plastic top, and a wooden base, and runs off a Euro style plug rather than a ZX81 supply, an equivalent one has been fitted inside the case. The case has a full travel Maplin keyboard. It also has an in-built 16K RAM expansion, to negate using the original box attached to the rear connector, which suffered from the infamous 'wobble' where a slight knock could wipe the computer memory. There are two switches on the back, one appears to invert the black and white, the other is marked H/R, which garbles the screen when switched.

The Maplin kit itself was a full travel keyboard, which connected inside the actual ZX81, which cost £21.95, a moulded case could be added for an extra £4.95.

Maplin could also take your ZX81, and build it into the case for you, at a cost of £29.95.

Manufacturer: Maplin
Date: 1982
