Funnily enough I bought one of these ages ago for two reasons. The first and silly reason was because this was the device that was used in the Shark PPC advertising. The second reason was because I could always reuse it to boost the power to a 7200 if I wanted to run BeOS on it.
The second reason was a folly for two reasons. Turns out I no longer owned a 7200. I had given it away and I mistakenly thought you could run BeOS on a 7200 when it was the 7300 it worked on (I still have one of those).
I didn't mind since I paid like $25 for it. It's been sitting on a shelf for ages gathering dust. Now maybe I could put it to good use! Except I don't have a Mediator board just a Prometheus. I seem to have very weird luck.
