The Motorola 68000 - a microprocessor ahead of its time
It was introduced in 1979 as a hybrid 16/32-bit CISC microprocessor, featuring a 24-bit flat address bus and a 16-bit data path. This design achieved over 1 MIPS of performance and outclassed contemporaries like the Intel 8086 in both speed and programmability. It rapidly became the engine behind landmark personal computers, such as the Apple Lisa and Macintosh, the Commodore Amiga, and the Atari ST, as well as gaming consoles like the Sega Genesis, due to its orthogonal instruction set, ample register file, and large unified memory space. Even after its discontinuation in 1996, the 68000’s architecture endured in embedded controllers, printers, and industrial systems, cementing a legacy that shaped subsequent CPU designs across the industry. ...
