Help: Making an ADB Extension Cable


Recommended Posts

Hello all,

 

I have a spare ADB lead which I cut off of an AppleDesign keyboard and an ADB port that I unsoldered from a scrap IIci 'board. I would like to attached them together to create an ADB extension cable.

 

Does anybody know what each colour wire corresponds to?

 

Red:

White:

Blue:

Green:

 

 

Pin 1 ADB Data   Pin 2 PSW Power on   Pin 3 +5V +5 volts power   Pin 4 GND Ground

 

 

Thank you!

Don't have that info offhand, but thought I'd mention a couple of things for you and the gang:

 

If you don't have one already, pick up a continuity tester, they're invaluable for the hobby and the fastest way to determine pin assignments/color coding for this kind of thing.

 

Consider ordering S-Video connectors for this purpose.

 

Consider re-purposing (currently cheap as dirt ;D ) PS/2 KVM Switches with panel mount version of same. They're the equivalent of your extension cable,but for several Macs at once in that config.
