So far, that 1.3GHz P3 looks incompatible.
I've got a Micron Millennia Max GS PIII 733 133FSB with a TazerII-Tyan S1854 Via 133a 4x motherboard. I was thinking of replacing the CPU with one of the later PIIIs like a 1.3 GHz for ~$80 (what was the last PIII's speed?). Sounds like a cheap performance boost. Can I just put any PIII on that MB or are there other considerations?
Actually, what has made you decide to upgrade your CPU? I have a similar situation in that I am stepping up from a PIII 733MHz to a PIII 1GHz on an Aopen AX34 Pro II MB. It's the fastest compatible chip that I can get for this board, according to Aopen. MY reason for the upgrade is to install a DVD writer. The better DVD RAM drives all require at least a PIII 800MHz or better processor. My hard drive space, memory and all the other critical specs pass, but my processor is going on 4 years old! If it wasn't for that, I wouldn't even bother with the upgrade; my machine is running fine (knock on wood). Think about why you want to upgrade the processor - you may find that putting your money towards a new P4 machine would be a better idea.
If you do decide to upgrade the processor, check Tyan's website for jumper settings any whether BIOS information needs to be altered.
Upgrading your processor will depent upon serveral compatability issues. They are:
1) Which version of the CPU interface you have:
A) Slot 1
B) Socket 370 FCPGA (Coppermine Processor)
C) Socket 370 FCPGA2 (Tualatin Processor
2) Which chipset you have on your motherboard, and whether the chipset will support the processor you want.
The good news is that you can definately upgrade your system, the question is just how much. If you have a 370 FCPGA socket you can get an adapter to mount a 370 FCPGA2, if your chipset is comptible, The Tualatins have processor speeds up to 1.4 Ghz. Even if your chipset will not support a Tualatin, you can still upgrade to 1.0 Ghz coppermine processor. (once you find one)

The Moto Z2 Force is really thin, with a fast processor and great battery life. It can survive drops without shattering.
