Whoa, that helped a lot ;)
The main question is: Can the TI link port hardware be used with the Casio
protocol?

Well, then the converting should be reltively easy...but still, there are
many other obstacles...

There are online asm schools, books etc. You could start at www.ticalc.org.

The whole idea, because dozens of IR link designs have been tried by me and
many others, and none of them has worked well, mainly because the link
cable has two data lines which are both bidirectional. It's technically
quite difficult to send such data over an IR link.
