Hi All,
I'm after some more info on Permedia 2 GFX chip...
I require ( XP4020GFN Hardware Reference Manual ); can't find it anywhere.
Also need info on CyberVisionPPC Hardware Reference Manual :
eg:
Pinouts on the Connector to the CyberStorm PPC card.
How it functions (what mode it's in ? )
PCI slave , PCI Bus Master with DMA + Sidband , or just some kind of flat adressing.
And why is the bus so SLOW; should be loads faster.
Thanks in advance ....... Wol..

I'm sure I have all the Permedia 2 documentation and errata somewhere but as for the card itself I doubt that's readily available. I too have wondered about the apparent bus speed but IIRC, VRAM write speed on the CVPPC is significantly better. _________________
