Wow!  Just when I start thinking there's nothing else to build...

Just a thought, but can't the propeller handle a serial port or two?  Vince Briel's terminal runs two serial ports off of the propeller.  The Zeta accessory board also does this (and drives an SD card too).

There was an outcry for a serial port.  These unfortunately take up board real estate badly.  I opted to add the (again well proven) USB port chip that we used on our Serial I/O board (http://s100computers.com/My%20System%20Pages/Serial%20IO%20Board/Serial%20IO%20Board.htm ).  This 18 pin “chip”  takes up little circuit room and actually is easier to interface to a PC than a serial port. USB the serial cables are also very common.
