I just bought a DWL-G520 for the princely sum of 99p (+ £1.99 postage) on eBay.
I can try it in my 4000 if you like...?
(Edit: I have a Prometheus though so not sure how much that'd help...)
Thanks, but I don't think the Prometheus will do DMA properly until the vapourware DMA hardware upgrade/reflash emerges. Like the G-Rex, I couldn't even get the PIO-only Prism-II cards to work properly in my Prometheus.
Maybe atheros5000.device would work under OS4 with a Mediator however (that has native OS4 drivers, doesn't it?).
