Sinclair ZX81 with Unbranded Case

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.

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.

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.

Manufacturer: Maplin
Date: 1982
