1541 Speed Test by Zibri - Need to diagnose an issue with your sick, well here's a tool that can help.  Although it seems straight forward, I highly recommend reading the documentation, especially if you don't want to bork the disk your testing with.

Sound 47 by Frank7 - Although I have this in the hardware testers category, it's probably more of a demo of the SID chips capabilities, either way, it's pretty neat to hear what the little sound chip can do.
