Still working out portions of the design.

I do have a single port 6551 RS232 Pak unit of which I've sent a few 
testers out.  Ladd and Michael Brant have them.  They have the 230K mod 
installed and as much of the Sockmaster mods I could figure out how to 
implement thus far.

A few folks are asking for the single port version, so I'm figuring up 
sales prices.
