What you've got is a dead keyswitch.

I like the ][e keyboard; it has a great feel to it, especially compared to

my GS keyboard. The trouble is that with discrete keys, you've got some

63 little switches to fail.

They're not hard to replace; I've probably bought enough keyswitches for

Mom's ][e to buy two or three new keyboards (anyone know where to get one

for, say, $70? "Genuine" type ][e keyboard? Jameco dropped them from the

catalog right when I was about to order one!)

Anyway, the last time I checked, keyswitches were about $10 each retail

for the Alps Long-Stem switch. That's the same switch as used in the Mac

Plus keyboard, so they are still available.

To replace the keyswitch:

Remove the screws from the bottom of the ][e case. Remove the case. If

you have a classic ][e (beige), the keyboard will be supported on two

triangular supports attached to the base plate. On the "platinum" ][e,

the keyboard is attached to the upper case.

On the beige ][e, save yourself a lot of grief before going any further.

Get a marker and scribe the supports at the edge of the keyboard assembly.

This will allow you to get the horizontal alignment right when you put it

all back together; this keeps you from getting hung with stuck keys later.

Remove the four screws holding the keyboard, and disconnect it from the

motherboard. I suggest unplugging the ribbon connector from the end of

the keyboard so it will be out of your way.

Remove the keycaps from the bad key and from the surrounding keys by

pulling them straight off. Examine the keyboard, and locate the two

solder connections on the back directly below the bad key.

At this point, I usually mount the keyboard upside-down on the support in

the computer, since it provides a handy support which also protects the
