digital servo controller to offload the Parallel Port?

[John Griessen <john_g-at-cibolo.com>]

Hello y'all,

If a feedback loop is too much for emc on a PC via standard ports, has
anyone made a microcontroller digital servo loop controller for emc
yet?  Who wants one?  How many?  I can design such and nowadays it can
even be lower cost then microcontrollers/memory when you design it into
a FPGA system chip.
