[comp.sys.mac.hardware] Smoked ADB port help?

t-jacobs@ced.utah.edu (03/19/91)

My ADB (Apple Desktop Bus) port is smoked on my cx. It costs $400 for a board
swap!!! OOOUUUCCCCHH. Anybody know what component(s) on the mother board need
to be replaced? If it's fairly straight forward I can handle it myself.

Any help or references at would save me lots of bucks and anguish.

Thanks,

The November 1989 MacTutor has a detailed article on how to repair the ADB fuse which almost certainly is what is blown.
