This was a car boot purchase, a Pre Computer 1000 than can run off batteries or a mains adapter. It didn’t come boxed and as usual with car boot purchases is always a gamble.
When tested, it worked. Originally this was sold in the late 80’s to early 90’s for children wanting to learn and use a simple computer. It has a slot in the left hand side for additional cartridges although these seem to be quite hard to come by.
The full qwerty keyboard lets you input answers to questions on a simple LCD screen with various beeping noises indicating activity on the computer.
