Here are some applications I've written for the 3Com Audrey. Read all about this wonderful little toy on AudreyHacking.com.
PhJuke MP3 jukebox app
Audrey MP3 apps, version 0.2, 2001/11/23, 137967 bytes (PhJuke is much better than anything in this distributeion.)
The original version of my Caller ID server, version 1.2, 2001/11/29, 17101 bytes - this interoperates with Jeff Kohn's Windows application, CallerID Sentry. This code has been merged into ACID 2.0, which offers a nice GUI. Get ACID instead unless you want a very small barebones caller ID app.
