Apple Specs > By Processor > 68LC040 Processor

Update Published December 12, 2025

Every Apple Mac that uses a 68LC040 processor -- also called a 68LC040 CPU (Central Processing Unit) -- is listed below.

Apple first released Macs that use the 68LC040 processor in 1993 and continued to sell Macs that use this processor until 1996. The 68LC040 processor is the same as the full-fledged 68040, but the "LC" variant -- for Low Cost -- lacks an FPU (Floating Point Unit) to reduce the price tag (as well as reduce performance).

Click on a specific model for its complete technical specs, configuration options, identification details, and more.
