It seems to me that an AGP card might be a better option. The C8000 manual indicates that it has one AGP 8X Pro 110W 32-bit slot. It looks from connector pinout in the Technical Reference Guide that the C8000 has a AGP 1.5V motherboard (pins 9, 16, 25 and 28 are VCC 1.5). The HP "supported" FireGL cards are 1.5V, 0.8V: http://www.synthmind.com/737-18872ATIAGPGraphicsCards-AGPComplianceDetails.pdf So, I think one needs to look for a 1.5V or Universal AGP card. The first ATI AGP card to support 1.%V appears to be RAGE 128 PRO. These articles give info about AGP slots and what works electrically: http://www.playtool.com/pages/agpcompat/agp.html https://en.wikipedia.org/wiki/Accelerated_Graphics_Port Dave -- John David Anglin dave.anglin@bell.net
