  Sorry if this is a FAQ, but I don't have time to go searching everywhere for 
the FAQ post, and I'd like to get started on this ASAP.

Anyway, the thing is, I was browsing through some of the programs on the 85 
archive and noticed that data can be sent by a program through a COM port to 
the calculator.  

Now, instead of paying the $70 that one costs directly from TI, would it be 
feasable to make on by combining a stereo headphone type jack with a serial 
cable?  

If so, has it been done?  If so, could you send me technical specs on it so I 
don't have to figure out which wires to connect to which other wires.  And if 
this kind of data isn't available, would someone be willing to send me a 
diagram of the pins on a serial plug so I don't have to just mindlessly probe 
to find what the right connections are?

Thanks ALOT in advance.
