Apple Macintosh LC 475 Overclocking to 33MHz

The first video up is the mod itself, rejiggering some resistors around on the mainboard.

Benchmarks, everyone loves a good way to compare systems before and after overclocking. Here’s what to do to get your LC 475 up from a measly 25MHz to a beefed up 33MHz. It’s a 15% – 30% performance gain for free! Based on benchmarks on my stock 25MHz chip running at 33MHz.

Dude, where’s my FPU? Missing FPU in my 68040 is definitely cause for alarm. Counterfeit processor… Blighters!
