This design technique promised faster CPUs.
In the late 1980s, the computing industry began to turn away from the legacy 1970’s CPU architectures in favor of new trends, like Reduced Instruction Set Computing (RISC). PowerPC (1994-2005) The Apple Power Macintosh 6100, the first PowerPC-based Mac. The final Mac model to do so was the PowerBook 190 in 1995. Overall, at least 72 different Macs used 68k CPUs.
These increased in speed and complexity over time. Over the next decade, new models of Macintosh computers began using successors of the 68000, including the pure 32-bit 68020, 68030, and 68040 chips. This delighted Steve Jobs, who wanted to upstage the Lisa team. The Apple Lisa used only a 0, but the new Mac prototype could run at 8 MHz. However, after a designer saw the a mazing graphics routines that were being created for the 68000-based Apple Lisa, the more expensive 16/32-bit 68000 was used. While in development, an early Mac prototype used an 8/16-bit Motorola 6809 CPU.
In 1984, Apple released the first Macintosh computer (called, unsurprisingly, the Apple Macintosh). Motorola 68 K (1984-1995) The Apple Macintosh (1984) was the first Mac to use a Motorola 68k CPU.
