Yay! A tachometer for your computer. Basically, this is an RPM gauge, like the one found in automobiles, but it connects to your COM port and measures your processors speed. The tach they sell is an actual car accessory; you can purchase the software seperatly and use your own Tach, if you wanted to.
I decided against cutting the case to install the tach, and instead ‘mounted’ it in my computer desk. Not as pretty, but more convenient.
I totally enjoy the tachometer. Now, if only I could race other computers.
