does anyone know how to tell a Sawtooth board revision?

I am going to be getting a G4 Sawtooth from MacDan on the forum in a trade. I would like to figure out how for him to find out easily what board revision it has. I kinda need to know what uni-north revision it has. Is there a location on the board that will tell me this? what about the model number, and where can it be found?

if you have any info, it might help as I want to see if I can use a Dual CPU 450Mhz in it. It's a CPU rated for the Gigabit ethernet, but I want to know if it will work. I am not sure if MacDan has a video card for the system so I don't know if he can get it to power up.

If all else, i can just wait and hope for the best and wish that the card will work.

if not, anyone interested in buying a Dual G4 450Mhz CPU? It's guaranteed to work described by the seller...

Go to the discussion about using 8.6 on a Sawtooth. In that post I bring up the issue of the 2 motherboard versions used on the Sawtooth. I show you how to use Apple System Profiler to determine what Uni-N revision you have. The instructions I provide are for the OS9 Apple System Profiler but I assume you can get the same info under OSX. If not, some of the cpu upgrade companies have a OSX utility that will tell you whether the motherboard supports dual CPUs. Here is one such utility. Here is another. Uni-N revision 7 or later supports dual CPUs.

I also provide the part numbers for the 2 different versions of motherboards used. The assembly number should be printed on the motherboard. On mine it is located near the cpu. I own a Sawtooth that supports dual CPUs and I believe it uses a version 2 motherboard. I have seen it suggested that the only difference between the two versions is that version 1 did not support dual CPUs while version 2 does. However, I don't know this for sure. Stated another way, just because the motherboard is a version 2 does not guarantee it supports dual CPUs. The only way to know for sure is to use Apple System Profiler to check what revision of Uni-N is used. However, if I had to guess, I would say that the version 1 motherboard probably did not support dual CPUs while all version 2 boards probably did. But again, I don't know this for sure and the only way to know for sure is to check the Uni-N revision being used on the motherboard.

Lastly, there may be one other clue as to whether the Sawtooth supports dual CPUs. Look at the power supply. I have also seen it suggested that the Sawtooths that had motherboards that support dual CPUs will have a 237 watt power supply while the earlier Sawtooths that only support single CPUs will have a 208 watt power supply. If you can't power it up to check the Uni-N revision, check the power supply label to get the wattage as well as checking the assembly number printed on the motherboard.
