Not really sure where to put this question or if I should post on another forum as 90% of the posts here are pc related.

I recently picked up a power Macintosh 7300 missing its cpu, bought a 200mhz one, replaced the battery and found a ati radeon 7000 mac 32m pci put it all together this morning and no video.

I get the apple chime, and if i hold the command+option+P+R keys it will reset the pram as you can hear it reboot.
at this point i realized i did not have vram in the computer, So that makes sense that it will not display video from the motherboard, but I thought the radeon card would display video...

Any one can confirm my suspicion that you need vram no matter what?

thanks for any input.

I own a 7500 with a separate video card and that still requires vram on the mainboard, too.

Thank you for the info, It figures that would be the case.
I just ordered 2mb vram, thanks!

The onboard video is still decent. the radeon 7000 is quite a bit overkill.

It is a mistake to think you can solve any major problems just with potatoes.

If it's anything like the Power Mac 6500's integrated graphics, it's probably good for nothing but 2D and would warrant a Voodoo2 or flashed Voodoo3 PCI to complement it.

Normally, I wouldn't say that the Radeon 7000 is overkill, but if it's not getting anything beyond a 200 MHz 604e, then that won't cut it for games like Unreal Tournament and Deus Ex where you really do want a Radeon-era GPU... and a CPU that's at least in the 1 GHz range, x86 and PowerPC alike.

UT chokes on my Power Mac 9600 with a 400 MHz G3, as if the Rage 128 and Voodoo2 (I tested on both) are also inadequate, but I didn't slip in the Radeon 9250 PCI from my MDD G4 yet.

That said, the Power Mac 7300 seems like a decent machine for early software-rendered games. Absolute Zero, A-10 Attack!/Cuba!, stuff like that. MechWarrior 2 may be cutting it close without the Radeon (it uses QuickDraw 3D RAVE and thus benefits noticeably from better GPUs).
