What was the first 32-bit processor for a Mac computer?
The Motorola 68000 was the first Apple Macintosh processor. It had 32-bit CPU registers, a 24-bit address bus, and a 16-bit data path; Motorola referred to it as a “16–/32-bit microprocessor.” The Motorola 68020 was the first 32-bit Mac processor, first used on the Macintosh II.
What is the difference between the 68000 and the 68020?
The 68020 had many improvements over the 68000, including an instruction cache, and was the first Mac processor to support a memory management unit, the Motorola 68851 . The Macintosh LC configured the 68020 to use a 16-bit system bus with ASICs that limited RAM to 10 MB (as opposed to the 32-bit limit of 4 GB).
