[Coco] RS232 Pak needed

[Brian Blake]

Al,

Some have used a 16550 series chip. I think that's what Mark was planning
on for the SuperBoard (could be wrong, been a while since I've seen the
features).

Roger used the 6551 to maintain compatibility with the RS rs-232 pack and
existing software. Implimenting a parallel port is feasible, but, that will
impact compatibility with existing software that's designed to use either
the bit banger or rs-232 type packs.  Some people will argue that's not a
big deal, some will say it is.

Beyond that, anything else will be up to those who know how to design and
code for these things. Of them, I'm not one....
