Can anyone tell me why the 41 blanknut has a cover that partially covers the toggle keys on the HP 41 blanknut? Was this present on all blanknuts, or was this an option for certain users to prevent programming input? Also: is it removable without damaging anything (not tat I really need to, just curious.) Thanks,, Theo

Yup that's right. I also have had ones without it, and will be getting one in the mail soon that has one, so that made me curious...Thanks for the info! Theo

One of the primary uses for blanknuts was for companies that wanted to run custom applications. With a custom keyboard overlay and ROM module (or a program loaded from magnetic cards), a 41 could be given to a user who knew little or nothing about programmable calculators, but who had been trained to use the custom application. In such a situation the company's support team probably would not want the user turning off USER mode or fooling around with PRGM mode, because that would invite problems. So the USER and PRGM buttons were disabled, and many of the other keys were unlabeled so that users would not be aware that those keys could perform functions other than those labeled on the custom overlay. The calculator always would stay in USER mode and the keys only would perform the functions needed by the company's own special application.
