<br>Non-ADB keyboards use a mini-DIN connector with 5 pins. Non-ADB keyboards have a black power key between the brightness and volume keys. Non-ADB mice use a mini-DIN 8 connector. Non-ADB mice are rectangular. All NeXT hardware supports these peripherals with the original mono MegaPixel Display (N4000 or N4000A) or a non-ADB soundbox (serial number prefix ABN). The ADB monitor and soundbox cables will work with non-ADB monitors and soundboxes. Non-ADB monitor cables (part numbers 150 or 1532) and soundbox cables (part number 2286) only work with non-ADB monitors and soundboxes.

<br>ADB cables have mini-DIN 4 connectors. ADB NeXT keyboards have a flat green power button. ADB NeXT mice are rounded. Apple Macintosh ADB keyboards and mice should also work. ADB peripherals are only supported on NeXT hardware with ROM version v.74 (most turbo systems and some later non-turbo systems). You also need a newer mono MegaPixel Display (N4000B) or ADB soundbox (serial number prefix ADD). Additionally, you need an ADB monitor cable (part numbers 4534 or 4535) or an ADB soundbox cable (part number 4536).
