I wrote my own PDA software, and have used it with both a 302 and a 302A.
The 302 data stream contains wind speed and direction (which is pretty
close to what I calculate using my own TAS/GS based circling wind
calculation) and headwind component (along with a bunch of other data),
the 302A does not. Make of that what you will...

Interesting -- they must have given the 302 that capacity so it could
output to the 303.

Greg,

They gave the 302 that capacity so it could talk to the Compaq 15xx PDA
software and the 303.

Back in the mid 1990s, Cambridge to distribute Pocket Nav PDA software. It
was very simular to Glide Navigator (same author.) The "Standard" version
was/is free. The standard verson works well with a generic GPS like the
Garmin 12XL. The "Plus" version, which wasn't free, provided an interface
with both the Model 20 data recorder and L-Nav/S-Nav. The characteristics of
Pocket Nav Standard/Plus can be seen at
http://www.cambridge-aero.com/pocketNAV.htm.

The 302 interface provides enhanced capabilities of both the old flight
recorder and L-Nav/S-Nav.

Locally we have two glider still running the Standard version in combination
with a Garmin 12XL and EW Model D. Two pilots have 302s. One runs the
Cambridge software and the other Glide Navigator II. Two pilots have the new
microRecorder and run Glider Navigator II on their PDAs. I run Glide
Navigator II in combination with a Garmin 12XL and EW Model D.
