It will probably work, however running on a mb that old will likely cause issues. Number 1 being that the ssd will not run at full speed and will likely have it's speed fall over time.
It is also possible to use an adapter to connect to an IDE or if you want to spend a bit there are IDE SSD available. But again you will see limited speed increase doing this as the IDE controller will limit the speed of the SSD.
I don't want it to sound like there's no benefit to upgrading to SSD(there certainly is) but just be aware that you will not receive the full benefit with your systems.
