CS 475 OC uses code from the Soft 475 Overclock project, and the Control Strip Module elements are based entirely on the CSShell example code created by Martin R. Wachter from 1994 (and used with permission, which was a challenge given 30 years have passed!).
This software only exists because of the overclocking routines written by MusterMann and shared on the 68kmla forums.

What it Does
CS 475 OC allows you to set the speed of your computer to 20, 25, 33, 40, 45 or 50MHz, by adjusting the system clock speed. It also adjusts various timings such as RAM, to help the computer run at these higher speeds. It is certain that not all computers will run at 40MHz and above, but some will. The computer will revert to its default hardware clock speed following a shutdown.

System Requirements

up to Mac OS 8.1
Compatibility notes
To use this software, you need an LC 475 or another Macintosh with the same chipset, namely, the Quadra 605, Performa 475, Performa 476, LC 575, Performa 575 or Performa 577. You must be booted in 32bit Addressing mode.
Built in timings within the Control Strip Module will pick slightly more agressive timings if you are using a model of computer that shipped at 33MHz and with 70ns built in RAM.
You will need an operating system with the Control Strip control panel installed. It generally came with System 7.5 and later, but I believe can be installed on System 7.1.
There is a compatibility issue that means it is usually not possible to change the resolution of your screen using built in video after you have changed the system speed. It is recommended that you set your resolution to what you will need before setting the speed.
Warning
This software overclocks your computer and makes a number of components, particularily the CPU, PSU and some of the chipset, work harder and hotter. Make sure your computer is suitably cooled, consider adding a heatsink or heatsink and fan to the CPU. Ensure the lid is properly fitted when running with an overclock to ensure air flows over the logic board correctly. Any issues resulting from the use of this software are not the responsibility of the author/s.
