Got a TI99/4a for parts, but I was able to get it working again. It was missing the power slider, so here you go. Took 4 iterations to get it to fit right. As you can see, there should be no supports when printing.

This will also fit both the TI99/4 and black TI99/4a.

It will not fit the beige TI99/4a with the top slider switch.
