Hp42
Helt konge. Endelig en tekniksk HP kalkulator som er og ser ut som originalen. Love it. Hilsen hp-kalkulator bruker siden 1973 (hp45)
Resurrection of HP42S
I appreciate your effort to make and maintain this app. I've probably used it since it came and still use it as my ever favorite and only calculator. It works exactly as expected. Thank you!
Error ....
Some changes seem to be made in the app recently. It gives error messages: "Not a number". A good app has been unusable ( I've been using a real RPN HP since 1978...)
