Heh. No sweat.

Oh, most of the color 040 slabs came with sound boxes.

It also houses the DSP, which is pretty neat.

Fair enough. I don't know the details on doing that, and I think
chances of frying either the controller in the slab or in the
keyboard are middling to high, requiring a much more expensive
repair part.

Yeah, well, maybe someone else will know that what you want to do
will work. You're definitely trodding into territory I've not
crossed. (I'm a little wary of even mucking with the custom data
acquisition board filling two slots in one of my cubes; I got the
machine from's neurology department.)

Maybe? Like I said, I'm not interested in breaking the hardware I've
got. :^>

I have no idea where the "I'm alive" circuitry in the monitor that
lets the CPU board continue booting lives.

It's a DSP chip, the keyboard and mouse controller, and a speaker.
In a cute, black, triangular box. With that evervescent NeXT logo on
the front.

Yow. Um, there're a couple other reliable vendors, but there are
also a couple you should not, under any circumstances, buy snake oil
from. I don't have my list handy (it's in the head of a friend ;^>),
but I'll get back to you.
