Re: Where to find the little red rocker switch for Speed up in HP41 Message #2 Posted by Meindert Kuipers on 4 Mar 2008, 2:51 a.m., in response to message #1 by PeterP
Peter,
I the good old days I used to sped up HP41's myself. I used an internal reed relay to do the switchover so it would not be required to make holes in the case. The calc would always run at the highest speed, except when writing magnetic cards. A small magnet would then switch the HP41 back to normal speed.
Today I would not do any modifications to my precious calculators anymore. The slower it runs, the longer you can enjoy it ;)
