I used to own an original TI-30, and it didn't come with a NiCad battery pack, it ran on a 9V battery. This was an ultra-low-budget machine, and the arrangement with the 9V battery helped bring down the unit price. They made this acceptable using two tricks I hadn't seen before in a calculator: first, after a certain amount of time, it would enter into a standby mode, where the display was turned off except for a decimal point moving left to right, and after some more time, it turned itself off completely, made possible by not having a sliding power switch.

But yeah, nothing odd about a TI-30 running on a 9V battery, that's authentic. A TI-58C, on the other hand...
