There are two versions, one with and one without the viewscreen port.

Minimal fixes.  No catastrophe.

In theory it's possible, but probably not.

As opposed to what?  You didn't do that on old calculators because the
assembly was a hack.  The 86 has openly allowed assembly, so that is the
command you use.  There are assembly programs that act as menus to the other
assembly programs that you have.
