Codenamed the ZX83 (notice a theme?), the QL started development in 1981 with a built-in CRT screen! Sinclair soon realized that it was over-ambitious and (maybe) too expensive to produce, so they just went with a normal desktop design. The QL, which stands for Quantum Leap, was the first mass-produced personal computer to use a Motorola 680x0 processor. It was designed to be superior to the IBM PC. Sinclair rushed the computer to beat Apple's Macintosh (which the computer was on par with) by a month. Launch was on 12 January, and orders were being taken for purchase of the machine. They promise to have them delivered in 28 days. The problem is, no prototype was made, so you could never call this thing "ready for release". In fact, it wasn't until April that the QL was first delivered, slowly. When it WAS first being shipped, early versions of the firmware had a number of programming and reliability faults with the Microdrives. Samsung-produced systems solved these problems, along with other companies long after the death of the QL. Users of these computers reported the computers working very well with the Microdrive 17 years after, but didn't change it's negative reputation.
