The Logic Board In a previous article, I mentioned that I had a Quadra 605 logic board with a bad microprocessor. The 605 uses a MC68LC040RC25, a 25 MHz 68040 without a floating-point unit (FPU).

Thought your older Intel Macs running on Lion all the way up through Mojave could no longer have a modern, functional web browser?
