trying to boot my PowerWave...

[wood_e]

SO I have a power wave with an XLR8 (I think - not sure) G3 300 card in it. I stripped the parts long ago, but today pieced it back together. I lost the speaker though. I tired booting it up and nothing, then reset the cuda - then I get gray for a split second and my mouse then the screen goes dark, then back again.

I switched the power off again and took the PRAM battery out and reset the cuda. Nothing happens now - this is a real bummer since I bought 2 10,000 RPM SCSI drives today

I have an adaptec card in it that supports 68 pin connections, an ATI 4MB card and I don't know how much RAM. It's all seated well. The cache DIMM is not in, and I seem to remember that you might need it in there for the compy to work with a G3 upgrade...

Anyway - anyone have any other ideas besides getting a new PRAM battery?

the pram battery seems to be a MUST with old powermacs. Especially the PCI models. Generally, they won't show screen, but there are a lot of other things that can happen without a PRAM. Worse case is that it doesn't boot.

I think you need to get a PRAM battery before you proceed. The PRAM battery is kind of a MUST on a mac pre-G3 era. So yeah, go ahead and get one

You might want to see if you can use an ATX PowerSupply and see if it's the PSU that went down on the machine. As far as other things, I don't know what to tell you.

thts weird, my umax c500 boots fine without one!

Just ordered 5 PRAM batteries for about $18 - We'll see what happens.

Is the PowerWave's ROM on a DIMM or soldered down? It pretty much goes without saying that you need a ROM present...

Of course, if your machine chimed at all, then the ROM must be present. The machine doesn't know how to make the start-up chime without a ROM in place.
