HP-42s emulator (hardware) link



#3

HP-42s emulated

bruce


#4

That is interesting. It's clearly not a "product," but a hobbyist project. I doubt those switches are going to give the same service as the original keys, either. But it is very cool. Click on the "Calculator" category on the right hand to get all the earlier blog entries regarding this project. He's got some interesting ideas for extending RPN, too.

Regards,
Howard
