Note: TI made a number of calculators with the rechargeable pack in this case; this battery door should serve as a replacement for them all. Check your model and explore the links below.
I had to dive into the OpenSCAD script of the customizable battery cover I remixed this from to get it just right. It may not be perfect, but it snaps right in there, keeping the 9V battery in place(the original battery pack is lost). I think I may replace it with a rechargeable Li-Poly battery and charge/boost circuitry. The original socket is just about right for a micro-USB port.
Vintage Texas Instruments Programmer calculator from 1977.
