Yes, I forgot about that. Which reminds me - did you ever play with  
the shark's TV output?

Hmm, I /think/ at least a handful PReP and CHRP machines had an x86  
emulator in ROM for just that purpose. The PowerStack-II  
documentation mentions it too but I doubt it's there because only a  
handful graphics boards I tried actually worked, and those which  
worked coincidentially had AIX drivers as well and finally, the  
Cirrus board that came with it had an empty ROM socket so I guess the  
firmware just knows how to deal with the Cirrus, Matrox and S3 chips  
used by Motorola and IBM.

Sure, I've got a pretty good idea what needs to be done and I might  
even have the time to finish it.

have fun
