[rescue] NeXT & Sun Monitor

[James Rice]

This is true of the connector at the slab.  The "Y" cable has 2 male 
13w3 connectors abd a male D19 shell connector.  One of the 13W3's 
connects to the slab, the other to the monitor.  The D19 connects to the 
soundbox.  Without the sound box, no keyboard, no mouse and no power on 
signal to the slab.  No monitor connects directly to the slab without 
interposing the soundbox.  Connecting a Sun monitor directly to a slab 
will let all of the magic smoke out.

You can use either a ABD or a non-ADB sound box with the same Y cable 
and the proper keyboard and mouse to match.
