Title: NeXT Computer N4000B MegaPixel Display Monitor: Power button working, keys don't

Hi,

This is the set-up:
Black & White NeXT Workstation,
NeXT ADB keyboard model N8001-3658,
NeXT Computer N4000B MegaPixel Display Monitor,
N8003 Mouse.
All parts are checked separately and are working,
accept for the key input. When I type, nothing happens.
(Power button of the keyboard works.)

Will the problem be inside the monitor?
And if so, what part of the monitors logic system is responsible for the key input?

Thanks in advance for your replies.

Cheers
Han

There is a sound board inside the monitor... there may be an issue with that.

Is your workstation a turbo model? Only turbo machines work with ADB.
