I'm pretty sure its a PowerMac (604[e?]) processor card but I can't tell. From the looks of the first image, possibly a dual processor one.
The other side is almost completely covered with a heatsink but has the following text on it:
apple computer, inc
daystar Digital, inc
820-0850-01

All I've got at the moment is photos (the card is at home, I'm at uni) but I can probably get more tomorrow.

Thanks

taking a few from the front and the back stright from above, with no silly angles and good lighting will help a lot :)

oh yeah, and keep the camera steady too, it makes it much easier to read :)

You'll can blame my brother for that. As I said, I don't actually have access to the card. I'll see if I can get him to take some better ones.

a google search on all those numbers turned up nothing - so dunno sorry - you should be able to tell if you can take the heatsink off though

Theres a number printed on the side that looks a lot like an apple part number.

600-4637

Google doesn't really help

I was looking at the PN6500 number myself..

Apparantly the heatsink needs a special screwdriver to remove.

Powermac 9500 upgrade card made my Daystar Digital Inc by the looks of it

certainly could be a dual processor card, possibly faster than 233Mhz, (266, 300?)

Thanks. I might get my brother to stick it in a machine now and see what happens.
