Question about Texas Instruments TI-83 Plus Calculator
In Mirage, it is possible to block access to the memory menu. When you are in Mirage, push the ALPHA button and it will bring up a list of options for the OS. Select the option that says Tasker and Key Hooks. There is an option in there that allows you to block the memory menu from access. If there is a check in that box, that is your problem. Just remove the check from that box and you should be able to access the memory menu on your calculator.
