The TI-86 is very similar to the 85. It's just that there are 16 rom pages
and 8 ram pages. I don't know if that's a big problem, but that's the
biggest difference
The lcd is not driven by a port. It's exactly like the 85: memory mapped,
and it's even at $FC00 also!
I doubt I would have enough time to test it myself, but just ask on
assembly-86 if you need some testers.
