Found the code tag thing by chance, then scrolled down and saw it pointed out for me.  Duh!

This code has undergone one update/replacement already - killed a font that was in DATA statements in favor of BLOADing it. 
I'd like to use _PRINTSTRING, but I have to expand the font in the vertical direction for the number display.

It works better if you plug it in.

This might be good link to manual (not secure), unless Richard has better?
http://83.156.189.247/ti58c/download/doc/LRNen.pdf

Dang! can't save a program? Can you emulate a printout from calculator?

Following the first steps in programming manual above, looks like the keys aren't all working yet.

The program clear function doesn't seem to be, nor picking up 2nd and the PI in program. SST and BST look OK.

Nope, Lst not working either, eh?

This is cool and ambitious project of course it will take awhile to get right.

True, I didn't take the simulation all the way to the end.   The program that's in there, under label E, works.
The E for Error thing is wonky - getting some weird INF (infinity) display beyond 10^99 too.....
It works better if you plug it in.
