The DA15 is for DSP I/O. The monitor port is a DF19; you must use the
monochrome NeXT MegaPixel monitor (N4000, N4000A, N4000B) on this
machine. All the human interface logic is in the monitor; it's where
the keyboard plugs in.

You're in a little better shape with the Color. You need the SoundBox,
which houses the HCI logic that would normally be in the monochrome
monitor, and Y-cable which splits out the video and HCI signals, and
connects them to the appropriate device. Once you have that, you can
use any number of multiscanning monitors with it. The original
specification on the NeXT Megapixel 17" color monitor is 1120x832 @
68Hz (the turbo does 72Hz) with composite sync on green.
A Sun monitor isn't likely to work on any NeXTstation because of the
sync-on-green thing; an SGI monitor is likely to work instead.
The connector is a DB13W3.

SOME NeXT machines can use ADB. You need a NeXT with ROM revision v.74
minimum, as well as either the N4000B monochrome monitor or the ADB
SoundBox (s/n ADD.....), as well as the ADB monitor cable (part numbers
4534 or 4535) or an ADB soundbox cable (part number 4536). The ADB
cables can be used with a non-ADB system as well; the reverse is not
I do not know if the power key on a Macintosh ADB keyboard can be used
to power on a NeXT, which may mean you would have no way to turn the
machine on or off without a NeXT keyboard, ADB or no. None of my NeXTs
support ADB, so I can't try it.
The NeXT ADB parts are visually distinct from the non-ADB parts; the
ADB keyboard has round 'chicklet' type keys for the
power/volume/brightness buttons , whereas the non-ADB parts have
regular keytops. Additionally, the power key on the ADB keyboard is
solid in color and bright green whereas the power key on the non-ADB
keyboard is black with green legending. The ADB mouse is known as "the
batarang", as it is round with trapezoidal buttons flaring dramatically
out the top. It is quite obviously different from the traditional
rectangular slab that is the non-ADB mouse.
Hope this helps.
