Ahhh, sucessfully updated the #firmware of my HP-15C CE #calculator! Checksum/Date before: 9090h/2023-01-05. Checksum/Date afterwards: 0A0Ah/2024-06-03. ✅ – HP (Moravia) addressed several bugs (including those in the hidden HP-16C mode) and worked on the keyboard debouncing. – Will test now … #Calculators #PocketCalculator #HewlettPackard #ScientificCalculators #hp15c
