Motorola 68060

The Motorola 68060, also referred to as the 68060 or '060, is a 32-bit superscalar CISC processor that was produced by Motorola's Semiconductor Products Sector with the intention of superseding the widely-used Motorola 68040. However, it was never adopted by Apple Computer, which had instead migrated to PowerPC processors for its Power Macintosh line.

History
The 68060 was introduced in 1994 at 50MHz, which was used in the Amiga 4000T computer. Later versions ran at 66 to 75 MHz. DayStar Digital announced the Turbo 060 upgrade card for 68030 and 68040-based Macs. However, aside from clock speed, Daystar staff reportedly observed little or no performance improvement and the product was cancelled. DayStar instead released the Turbo 601 upgrade card, which was based on the PowerPC 601 processor.

Variants

 * Motorola 68LC060 - a low-cost version without a built-in floating-point unit.
 * Motorola 68EC060 - a lower-cost embedded version without built-in floating-point nor memory management units.
