Burr Brown TM8500 control for propeller?

I have an old rs232 input device with a two line feedback screen and I want to get off on the right foot with pin selection so I can eventually add an sd disk platform for multifunctionality. Any help I can get on Disk OS or compatibility w/my TM8500's protocol would be wonderful. Point me in the right direction, if you know what I mean!

Thanx, WRQ9

    What is a feedback screen? Do you mean it's a display to the user? Is the display driven directly by the keyboard, or does it show text sent back to it?

    Generally, serial terminals run on pins 30/31 to match the TTL232 interface on the board. Start there, and move down to 26/27 if you can't share.
