Different CPUs on different spacecraft, mostly running a custom spacecraft operating system (SCOS). Google 'bektek' and 'pacsats' and you can find lots of information about the satellites--old and new.
For eample:
http://www.amsat.org/amsat/sats/nk6k/msatmain.html
There is CPU and memory information there about the original microsats...
Tons of information out there, really.

What do they run in the satellite ?
Dedicated PC ?
Sounds a big task

Hi Andrew,
Theoretically, yes. Realistically, probably not.
If the "server" software is available, and be made to run on typical PC CPUs, the answer is yes. I can't recall if the satellite/server side of the software is available or not...search around. The client side software was called PB and PG, so search for those. Also, you can search for pacsat protocol. There is a *nix version of these out there, too. I think the source code is posted. But for the satellite side (server)--not sure.

Can these satellite protocols be used on earth ?

I also uploaded a file with WiSP. Hope you can download it OK.
It would be nice if other voice users did not transmit until the packet transmission has stopped though.
Patience gentlemen, please.
