At this point I have three HP-41s in various stages…

“Nutella” is fully functional.

“Haffnut” is non-functional but I think I know what I have to do. Here I have a picture of the battery + module block restoration in progress. The part of the keypad PCB that contacts the battery block needs thorough scrubbing w/ DeOxit.

“Frankie” is on life support in a medically induced coma. Not sure if he’s gonna make it.

Waiting for the 5 min epoxy to dry on my repair to my Frankenstein HP-41 #calculator. I like having a backup machine in case my daily driver breaks.

New addition to my collection ☺️😊 #swissmicros #hp41 #rpnftw #rpn
