Sorry Snappy! I forgot to get back to you. As you can guess from the lack of response, I decided to keep my WCF12. It has proven to be very reliable, high performance, feature-rich, and flexible - working with all my HPCs, Casio PPC, and Win98 and XP laptops too. So I'd keep it as my backup WiFi card, even if it's doing nothing. Hope you find someone else to trade with.
Bump for you though
PS Have you tried Monster Chinese? They have HPC2000 version. A lot of people said that CE Star is not very efficient. On the other hand it might be possible to hack the 3COM driver to use a different name for AYGSHELL so it doesn't conflict with anything.
