Beige G3 ADB problem

[Renegade]

Hi,
I just took my beige G3 DT out of the basement. It boots without any problem, but after a few tries the ADB connector ceased to work.
It could be a broken solder joint on the connector, but I was wondering if the Gossamer mobo also has a fuse for the ADB circuit.

Thanks to anyone who can help me with this.

To the best of my knowledge, Apple's never used a fuse with ADB, unfortunately. In the earliest machines it was possible (although not probable) to fry your ADB port by plugging in devices when the machine was powered on. By the time the PowerMacs shipped, ADB was hot swappable.

It's not uncommon for ADB ports to go bad, but it's almost always just the port itself.
