The TI-99 is a desktop computer, at first I thought it was a calculator like the TI-98.
TI-98? No such thing as far as I know. The TI-89, now. That is a calculator. Also a significantly more capable machine in virtually every respect.

Parsec was 2D horizontal smooth scrolling. It wasn't full screen, but the scrolling screens in this demo generally contains repetitive graphics, which would allow them to use a number of possible tricks. I actually downloaded and tried the demo on the Classic99 emulator, and it works exactly as advertised. Would love to see actual hardware demo though.
I have the real hardware ready to go, but I don't currently have an easy option for getting software from the internet onto it. I see they made a ROM cartridge version of it; if they ever make a run of those for sale I'll definitely grab one.

Well, Parsec is very far from this demo, if the window is small it's for speed. The demo is full screen, which is impressive. And Parsec is coherent with what the hardware had to offer for the 3D those years, like Elite.

Yeah, 16-bit data bus but only 16-bit address bus. So still has the limitation of 64k memory which was really the chief defect of machines of that era.
I wouldn't call it a defect. It's just a limitation, which could and did get worked around to a certain extent with various bank switching schemes.
