The QL was originally conceived in 1981 under the code-name ZX83, as a portable computer for business users, with a built-in flat-screen CRT and internal modem. As development progressed, and ZX83 became ZX84, it eventually became clear that the portability features were over-ambitious and the specification was reduced to a conventional desktop configuration. Based on a Motorola 68008 processor clocked at 7.5 MHz, the QL included 128 kB of RAM (officially expandable to 640 kB) and could be connected to a monitor o ...

The 68k line of processors have been used in a variety of systems, from Texas Instruments calculators up to critical control systems of the Space Shuttle. However, they have become most well-known as processors powering desktop computers such as the Apple Macintosh, the Commodore Amiga, the Atari ST, and others. Today, these desktop systems are either end-of-line (in case of the Amiga and the Atari), or are using different processors (such as is the case for the Macintosh). Since these desktops are now more than a decade old, the orig ...

The QL was the first mass-market personal computer based on the Motorola 68000-series processor family to be released, beating the Apple Macintosh by a month, and the Atari ST by a year. While clock speeds were comparable, the 8-bit databus and cycle stealing of the ZX8301 ULA limited the QL's performance. However, at the time of launch, on January 12, 1984, the QL was far from being ready for production, there being no complete working prototype in existence. Although Sinclair started taking orders immediately, promising delivery within 28 ...

Initial samples of the MC68000 were released in 1979. At the time, there was fierce competition among several of the then established manufacturers of 8 bit processors to bring out 16-bit designs. Intel was first, with the Intel 8086, but Motorola marketing made a point of the 68000 being a much more complete 16-bit design. This was reflected in the complexity. The transistor cell count, which was said to be 68,000 (in fact, it was named after that, although it was in reality around 70,000), was more than t ...

The standard addressing modes are: Register direct data register, e.g. "D0" address register, e.g. "A6" Register indirect Simple address, e.g. (A0) Address with post-increment, e.g. (A0)+ Address with pre-decrement, e.g. -(A0) Address with a 16-bit signed offset, e.g. 16(A0) Note that the actual increment or decrement size was dependent on the operand request: a byte read instruction incremented the address register by 1, a word read b ...
