1984.

It is said that Sir Clive Sinclair had a great hurry to get this futuristic computer out on the market, because it was the first with the new Motorola processor 68000. Close behind was, among others, Apple Mocintosh. Sinclair QL was an attempt to enter the business market, but in Sweden QL was no hit. Perhaps because it had some hardware problems. Many were also waiting for, according to rumours, the mysterious Amiga 1000.

This unusual computer has, inter alia, two new micro drives that Sinclair invented. It was a kind of secondary memory of 85 KB to 90 KB capacity (formated) with a closed loop and was relatively fast.

Thanks to Peter Westerberg for valuable comments.
