More EMC Conversations w/ Controller Boards

From previous posts I get the idea that servo motion control boards
like Servo-to-Go, Pico and similar boards are what lab people would
call a multi-i/o board: some DAC's, digital IO capabilities,
interrupts and clock-timers. (OK, not every I/O board has quadrature
decoders, but some have 24-bit counters which is getting close.)

Think it would be possible for a mere mortal to get EMC to
communicate with a MIO board over the ISA or PCI bus? I guess the STG
team managed to do it ... The thing is, these boards turn up cheap
once they're a generation down.

Thanks in advance.
