I'd love to, but it's very well hidden. I'm hoping someone has
it working on a similar moedel.  IBM's website says "soundblaster
pro compatible" at some points, and "crystal audio" in a  couple,
but I haven't been able to find anything else on their websites
r the documentation that came with it (which was a ultra-newbie
manual mostly with the trival diagnostics [problem: screen dark.
solution: turn on unit]).

I tried poking through windows, but it doesn't tell me any more about
the device than that it's crystal.

Is there any way to probe the chip?

boy is it fussy :)  But catting that file is just a habit I got into 
forever ago to test sound.
