In case anyone in interested, I created a zip file of the Zaurus feed. It is big, but it has everything I have ever installed on my Zaurus.
You can also add http://cyberphreak.com/zaurus/feed/ to your Zaurus package manager, if you need a proper feed.
Thank you very much for your sharing. I just got a Sharp SL-C750 and I’m getting familiar with it. This is my first time using this device; I’ve only used Palm devices before
