(Does anybody know where to find a 2.5mm-to-3.5mm adapter that fits in an 84+'s link port?)

If you have a standard 2.5mm TI link cable, you can put an adapter on one end of that and put the other end in the link port. It's pretty reliable (and gives more flexibility)

I recently got mine from radio shack, (I lost my old one). It was $10. Overpriced, but it works. It also has a third band for a microphone, but it didn't interfere.

I might give the audio-from-a-USB-drive idea a try.  I guess I need to learn how the MSD protocol works, though.

you can buy one from radio shack for $6.
Just make sure you have a sander and a steady hand, so you can remove some plastic from it.  As it is a tiny bit to big.

Note: NOT the plastic bands on the jack.

what calc you got?

really?
With my 83+ I did not need to modify my adapter at all to fit it in. It's a bit loose, though...

I ran into this problem too. Happily, the Pulse smartpen comes with a flawless set of 2.5mm headphones.

I've been mulling this over for the past couple weeks.  I think it should just barely be possible to play 8-bit, monophonic audio at 44.1 kHz, if the USB drive is fast enough at responding to commands.  (Hopefully it should be, seeing as these devices are designed to work at high speed, but I'm not sure.  It would be interesting to know how long the 84+'s USB controller waits to retry after receiving a NAK.)

This is, however, going to be a very difficult program to write: even though I know all the pieces, and more-or-less how they'll fit together, I expect it'll take a couple of months even to get to the point of being able to test it.  So don't expect this to be finished right away.
