Is the AT&T 6300 a rebadged M24? If so, the D

Yes, the AT&T machines were rebadged Olivettis. Different colour
paint, too, I think.
The Olivetti monochrome monitor was powered with 12V from the M24.
The colour monitor had its own internal power supply.
Beware of plugging a parallel printer into the M24's video
connector by accident (same "D" connector). It'll blow up
chips inside the printer due to that 12V supply!
