Do you not own a decent pair of scissors? Or wire cutters? (Preferred method for me)

This style of packaging is actually really common. They take two pieces of fairly thick plastic, form them in a vacuum-former, put the stuff inside, and heat seal the edges. It's quite strong, and very cheap.

fortytwo, you might not have loaded big enough files for it to try using them. It has no protection from trying to use the RAM pages that aren't there.

In my experience TI's Scientific calculators are not good. They have really laggy inputs, poor quality buttons, etc. and they don't do much.

I meant the file.

That's a lot faster than before! Good job!

Yeah. I can't even upgrade the OS unless I make my own Plus cartridge. It's not such a crazy idea once you see that the conenctor is just 2 2x10 .1' pin headers.

Do we know what the emulator is even named? From what I understand the standard way we checked it was there was via the ROM, which was its own file.

I would probably be pretty heavy into the 68k scene if I had a 92+ instead of a regular 92. Very few tools available for the old one.

That teacher screen actually hooks directly into the LCD signaling. There's no software interface involved. No way I know of to use that without interfering with the regular LCD.
The TI-Presenter used USB communication instead, so it worked with any calc, but it suffered the same problem this does, just like DJ mentions. It was very slow.
If you really want to get going, why not VGA? Just a few pins with some resistors and you can get a few colors.

It would have needed to be modified to accomodate the new screen, if the emulator itself was still there. For all we know the only remnant was the ROM file, not the actual emulation program.

well, if you want big LCDs, just use a small one and a projector. The issue is resolution, and the only reason that's an issue is because the transition is being handled by an arduino over a slow serial connection.
With more specialized hardware, this could easily handle far bigger, more colorful screens, as long as you don't mind it running at 1 FPS or less.

True. That's where things like partial screen updates need to come in. It would require more work on the calc's part, but the results would be worth it.

Well, we're still talking about a 96*64 screen here. That's only 768 bytes.

Yeah. Plus, they don't have removable keypads, but that can be seen as an advantage or disadvantage, as it's both easy IO access, and a failure point. (The connectors wear out)
