Info reqired CyberstormPPC / CyberVision

[Wol]

Hi All,
Has anybody got pinout information between the CyberstormPPC and the CyberVisionPPC card ?

I am thinking about making an adaptor to connect a generic PC Permedia GFX card to the Cyberstorm for a laugh.

There are lot's of cheap ones with better specs  on Ebay.

Thanks in advance
Wol.

That’s essentially what the G-Rex does, I think. I suspect this is going to require more complexity than a simple physical adapter, unfortunately.  Would be very cool if that’s not the case, though.

Have you checked the CS/CV manuals? I don’t know if there are schematics in there. Otherwise I’d suggest posting at EAB or A1K—there are a lot of people there with deep, low-level technical knowledge.

i wish it was passive, but there are a pair of chips common on the g-rex, bvision and cvision cards:-
Cypress Semiconductor  CY7C375I-83AC, and  CY7C374I-83AC

apparently these are both 128cell macrocell flash CPLD's - so i suspect they are responsible for completing a lot of the PCI glue logic. they certainly get hot enough!

i have no idea on CPLD programming or reading configs, so looking at it, you'd need to pull the config out of these chips and implement your own version...

I'd ditch my mediator, and put my CS-Mk3 in my A4k in a heart beat for a g-rex or equivalent though....

Thanks for the replies all,

The reason I am contemplating this is, the Permedia2 chip has a PCI 2.1 interface built in and the cards are very basic in design,
therefore I suspect the interface to the CVision card will be mostly Generic.

You could try and ask the chief in charge of this formerly famous company:

But be polite and ask for repair informations, schematics excerpt or similar. Donot mention a hardware build, as he will probably tell you he is already working on the same thing and then sue you, or at least scare you off...
