Yeah x.x
This looks like another one of those things that multiple people would benefit from ;D

DJ, you need a new cable D:

It'd be cool to be able to switch back and forth between TI and Casio cables though.

It does seem that way :)

Darn, I wish the cables were the same. My old 83+ cable is almost completely broken now so if it stops working forever, I'm gonna be stuck with like 4 Casio cables.
I would like to know: Are standard audio patch cables switched like the Casio cables, or straight-through like the TI cables?

That's an idea.  I don't know though...

Bump.  With the contest over, hopefully there's more time for someone to do something like this. ;D

Got a working multimeter today and was able to test it.
http://upload.wikimedia.org/wikipedia/commons/thumb/9/93/Jack_plug.png/300px-Jack_plug.png
The sleeves (labeled as 1) are connected.
The tip (3) is connected to the ring (2) on the other side.  Same both ways.
Looks to me like the 'data lines' are swapped...
EDIT: ndless to say I don't have a TI cable to do the same test with...but I'm suspecting that with TI cables, the tip on one side is connected to the other and the ring is connected to the ring.  w00t.

And yes, I'm aware of ↓↓
I think, what might make it work, would be some sort of hook that intercepts the stuff sent to/received from the link port, and virtually swap the tip and ring.
You can't cause the input from port 0 to change, though. That's how the OS gets the state of the link lines, after all. And also, you would have to switch the inputs/outputs on exactly one of the calculators.

I'm pretty sure Qwerty.55 has both calcs, and has messed with that.
I talked with him on IRC last night, he didn't mention messing with it but when I can I'm going to get a multimeter and find out what input for what part goes where.

I did mess with the IO cables a bit and got them to send signals. The TI kept freezing up for some odd reason while it was connected. Unfortunately, I appear to have lost my cable, so I'll have to buy a new one.

I was meaning the axe contest was over so hopefully an 8x programmer would be able to focus on something new :P

I was thinking more along the lines of a bit of software that virtually switches tip and the ring.  Which part of the plug is the ground btw?

*necrodoublepost*
I finally got around to converting a Casio cable..now all the parts connect directly to each other. (tip-tip, ring-ring, sleeve-sleeve) ;D
Haven't tested it with a calc yet, but the multimeter says it's working so whee ^_^

It would be funny to get TI an Casio calculators to communicate with each other in any way ;)

So TI cables and Casio cables aren't wired the same? Odd.

Ok, I tested it with a classmate's 83plus and it didn't work :/

Question:
Can someone with a multimeter and TI cable check which part of the plug is attached to what part on the opposite end?  (ie tip <-> tip etc)
reference:
1 = sleeve
2 = ring
3 = tip
