I promised to post this...

If you can't get a solvent to clean your bad keyswitch, here are detailed

instructions for replacing the faulty switch...

A Guide to Replacing Apple ][e Keyswitches

------------------------------------------

By Dave Althoff, ][. ([email protected])

NOTE: This document details the methods I have used to replace Apple

][e keyswitches. The procedure is fairly straightforward, but it

does involve completely disassembling your computer, desoldering the

old keyswitch, and resoldering the new switch. If you mess it up,

damage your computer, hurt yourself, or experience other

difficulties, I cannot assume any responsibility. As with any repair

or modification, proceed at your own risk.

Various comp.sys.apple2 correspondents have reported success with

cleaning Apple ][e keyswitches. I have not had much luck with this

myself, but I have replaced a bunch of the switches in one of my

][e's. The procedure is fairly straightforward. I have been able to

get replacement keyswitches from Micro Center (Columbus, Ohio) for

$10/each (Yikes!) for the Alps long-stem switch...which is also used

in the Macintosh Plus keyboard. Some ][e's use the Alps short-stem

key switch with an extension. If anyone knows a cheaper source for

these parts, PLEASE let me know!

1. Turn the computer off, ground yourself to the chassis, then

pull the plug on the machine.

2. Invert the computer and remove the Phillips head screws from

the perimeter. There are supposed to be three under the front

edge, and three more along each side edge. Some may be

missing (mine had only four). Do NOT remove the four smaller
