Well ih ave both a HP 48GX and a TI-85, the cable for the 48GX was simple 
to build, I had someone with the proper connector build one for me. The 
connector to the TO-85 uses what apears to be one of those head phone 
type of conectors. I can oviously link mine with another TI-85 but I 
really do not see how it would work with a mac or even a PC. I did not 
see a reference to a conection between a Mac or a PC in the manual, BUT 
if you know it can be connected with a mac, then it can be connected with 
the GS. Just have to have the correct protocols. Fortunaly for me, my HP 
uses Xmodem and kermit which both work well with ProTERM. Just hope there 
is no special protocol for the PC or mac if its out there.
