Hi there! So I decided to overclock my ti92, and i found this site: http://richfiles.solarbotics.net/Turbo92.html and I want to do the version with the switch. There's one thing, though: the diagram showing the circuit with the switch and the two capacitors makes me suspicious. According to the article it should allow one to switch between an open cirquit and 57pF, which would make the switch make the calc either go slower than before the mod, or not work at all, depending on the position of the switch. To my mind it should look a bit more like on the attached pic (I modified it). Also, what kind of switch should I use?
