HP Calculator Keys' Tactile Feedback
Is there somewhere I can find out all about the 'old' key switches that have that great tactile feedback (is it a rocker switch or something)?
I did a web search as well as a search of this HP Museum forum but didn't find anything about how they actually work. Regards, Paul My HPs: 11c (my current calculator; have bought 3 of them), 41cv (it disappeared somewhere along the way), 28s (old and busted), 67 (also MIA) |

RE: HP Calculator Keys' Tactile Feedback
I'm wondering if 3d printers have gotten the resolution small enough to where we could print individual keys like the older calculators. There are some now that can do multiple colors.
