controllers used in RP machines

I'm interested in knowing:

 - what kind of controllers are used in RP machines?
        (e.g., PC running dos and a delta tau motion board, or
        VME-bus processors running unix and real-time operating system, or ...)
        I believe that both the SLA and SLS machines use PCs running Unix, but
        I don't know what is doing the motion/laser control

 - what hardware/architecture features drive the control requirements?
        - multiprocessing, bandwidth or other technical feature
        - natural derivative of platform used for development
        - cost
        - wide availability of subsystems (boards, software, ...)

thanks
