hp41c overclocking

[Dave Frederickson]

When I installed the speed-up in my 41 in the 80's the only component I changed was the cap. There are numerous articles on this in the PPC Journals.
If you're clever you can install a small slide switch inside the battery compartment. The switch is in series with a cap and the two are in parallel with the cap mounted on the PCB. The cap on the PCB is the smaller valued part and the parallel combination equals the value of the original cap. This allows you to switch between 1X and ~2X speeds.
