That's right, they use a single cable from the monitor to the 19-pin
D-connector on the machine itself. That single cable on the monitor
carries power for the monitor, keyboard, etc.
It's not all ADB. There were two different types
of keyboards/mice
used on NeXT boxen. The early ones were NeXT specific, later ones
were ADB. The type of keyboard used depends on the computer and the
sound box. I believe you can use the ADB keyboards on some earlier
computers if you use the ADB sound box - but I think you might also
have to upgrade the ROM in the computer to work with the newer sound
box - but don't quote me on that.
I believe that's correct, but mine has a NeXT mono monitor so I've never
needed to test the theory. If it works, you may actually be better off
with the soundbox plus non-NeXT monitor solution, because most of the
the tubes in the mono monitors are now suffering from low emission and
are rather dim.
I am not familiar with the mono NeXT gear, having
never seen any "in
the flesh", but it was my understanding that the "sound box"
circuitry is in the monitor on these machines. So, you wouldn't need
the sound box, only the monitor. Of course, you're still equally
stuck, because the computer still doesn't have a keyboard port.
That's correct too, although I believe (subject to the caveats a
paragraph back) that you can use a sound box instead.
