Error code for startup on Digital Audio?

Hey guys, first time poster, and first time mac user. I just bought a G4 digital audio at a surplus sale, brought it home -- it didn't have memory or a hard drive, so I put those in -- and went to boot it to install Tiger... and nothing. It powers up, yes, but no display yet.

The light on the front of the machine is blinking an error code at me, and no matter how much I search on google, I cannot find a listing for these codes. It's a long blink, followed by a short one, and then it goes blank. Long, short, blank. It will keep repeating this until you turn it off.

I already tried resetting the PMU and this happens still.

Any suggestions?

 

Oh yeah...

It's a G4, Digital Audio, 733mhz... Forgot to mention the speed. Anything else you guys might need?

 

Took the RAM from a Quicksilver G4 that I got at the same sale... It went completely in, and clicked into place (the clips)... Do you think it could be wrong? I think I heard G4s can take PC133 as well as PC100... Is PC133 completely incompatible?

Ok, tried some more things...

Ok, the extent of my setup is as follows:

USB KVM Switch, mac is on 1 PC is on 2 -- works, I am using my PC presently...

Power Mac G4 Sawtooth Digital Audio, 733mhz...

I tried booting it again, holding C to boot from CD/DVDROM drive as the Hard Drive I have in there is a 40gb ATA but needs to be reformatted/erased as it was previously in a windows box. It didn't boot.

I turned up my speakers when I booted, and I do have a boot chime, a little "Diiing", and I can hear the fans running as well when I power the system up.

Any other ideas? Anyone know what the blinking light means??

 

ZOMG Success! I took some older memory I had from an HP that I had stuck into the QS (I mean hell, the Sawtooth will be my primary... why not give it more memory?) and it booted!!! No video problems or nothing. So apparently, the RAM was the issue. Why would the RAM for the QS be different than the Sawtooth? I mean, they're both SDRAM dimms... both slotted the exact same way. DDR Ram doesn't look like SDRAM, does it?? Anywho, going through setup procedures for the Sawtooth presently... wish me luck! Hopefully I'll be typing to you from a mac the next time!
