HP-65 diplay

Hello, everybody!

I am the proud owner of a HP-65.
The Problem: displaying the negative sign is not working
An idea?

Hi Fredo,

Do you fail to get a negative sign both when using the CHS key and
when a calculation results in a negative answer?
Also, are you able to negate an exponent?

Best regards, Hal

Hello, thank you for your response

Exactly, I can not see the negative sign with CHS and with the calculation giving a negative response
