How can it work with a mono slab, then, which already has its DSP on
the motherboard along with everything else?

P'raps. If the signal is just wired straight through, it's easy
enough, but if there's actually something complicated in between, it's
more work than it's worth.
I've got more keyboards than machines; I'll open up a keyboard and see
if I can see anything from that. (I couldn't infer anything from the
digital logic board in the monitor....)

Hm, where would it even plug in? To work with a mono slab and handle
the keyboard and mouse, it would have to plug into the monitor
connector. And I have no idea where it would get the signals to drive
the DSP from; there's a DSP port on the back, but it's the wrong
interface; that's the DSP<->world interface, not CPU<->DSP.
