It's on my keyboard, which is this old Key Pro thing with all these great programmable buttons, an 8-way d pad, and a built in standalone calculator (doubles as the num pad with a toggle button).
The turbo button is in the middle of the 8-way arrow button cluster and doesn't do anything, though.
Does anyone remember building machines in the i386 and i486 era where the cases came with LED displays for the system processor speed? They had a PCB and instructions on how to set the berg jumpers so the display would correctly display the cpu speed according to the turbo button position -
In on the 486 DX/33 would display 33 and out would display 8. On the DX/2 66 it was 16/66 (depending on the motherboard too). Later when CPU speed broke the 100 MHz barrier the displays had three significant digits but the first character was only two segments - capable of displaying a 1 only. :Q
I was picky too - some of the diagrams configured it so the 6's looked like b instead of 6 so I would correct that.
