The "255" HP-41C calculator was sold on eBay USA in 2018 for 41USD and shipped to Brazil. The front section is from a
newer HP-41C without TallKeys. The seller writes in the auction that the HP-41 has 319 memory registers.

2024: The restoration from "255" is done. The clone HP-41 calculator has now a correct TallKey front section and the correct
DDE Board with all bugs. Congratulation!
