I have a chequebook calculator by Olivetti. I haven't used it in years and have forgotten how to:

1. Set the password;
2. Once the password has been entered, how to unlock the machine to access my banking data;
3. How to get the machine to maintain the banking data that I have entered.

Can anyone help me? Here is a picture of what it looks like. I did manage to find the "reset" button in the back of the machine and I think that has something to do with clearing the password, but I'm not sure. I think this thing is like 20 years old! LOL
