A modification you may be interested in for the RIB. There have been reports of problems using the RIB on different computers. It looks like one of the problems might be a lack of negative voltage swing on the Busy out and RX (data out) lines back to the computer. You might want to try and change the value of R14 to 1.5k and R11 to 1K.
