NeXTStation Color DSP cable pinout

 Altho my Next color slab is not functioning at the
moment due to a flakey Monopixel monitor, I have
always been fascinated by the possibilities of the
Next sound system and especially the DSP port,
which I equated to the lauded capabilities of the Atari
Falcon and it's DSP port, aimed at the professional
musician market.

 The Atari ST was regarded by most professional
musicians, as the best music computer, partly
because of it's built-in MIDI Ports, and I tended to
view some of Job's Next dreams as trying to transcend
the Macs media limitations and blow it away.

 The Next DSP port seems to be the least documented
feature of the Next. What exactly is a Quix Daydream
and what can it do ? Do you know of other DSP
peripherals that would work with the Next? The Next
promos made much of it's sound capabilities.
