Look, the link protocol is response-syncronised.. i.e. it NEEDS 
another calc on teh other end. You can't use an asyncronous protocol 
with teh ti-85 due to the variable speed problem, though you could 
use an external crystal clock source. so the reason for a stereo 
track is to have one the clcok syncronisation and the other data 
trandfer. If you wnat to use a mono recording, you need to have an 
external crystal clock circuit attached to one of teh data lines, and 
the tape input attached to the other line and the calc can read data 
based on teh clcok signal.
