I've had a TI-85 for at least a year now and it's great.  I've used
it in conjunction with electronics courses because the instructors
seem to use it a lot.  I purchased the interface kit for the PC and
it works just fine.  That reminds me, I need to back up the calculator
again before the battery goes :)

I came across the following information in sci.electronics the other
day, it may be of interest to you TI-85 owners.  Some one has designed
a circuit that will allow you to interface with the TI-85 without
purchasing the official kit.  You get some text and several GIFs which
provide the schematic and circuit board layout.  Try the following
