How easy is it to take the plastic (?) keys
off of a keyboard without damaging either
the keys or the contacts underneath?
I assume, if they are taken off without
damage to them, they would simple clip back on?
I have never taken a keyboard apart yet, and
will no doubt need to someday. I probably won't
bother until a keyboard, or keys, starts failing.
Most of the time you can just pull them off. They're
held on as an interference fit, meaning simply
pressure. I guess there are exceptions though, so
don't keep pulling if it ain't coming off...
My experiment proved successful, though I hardly got
any acclaim for it :(. Several of the keys on my NEC
APC III's were unresponsive. So I took a plastic tub,
filled it with hot water, tossed in about a cup of
laundry detergent, roughly a litre of ammonia, tossed
in the keyboard, and left it there for several hours.
Pulled it out at one point, rattled all the keys, put
it back in for several more hours, then rattled once
more and rinsed. Left it by the air conditioner for
several hours and it worked fine afterwards. I saw no
evidence of corrosion due to the ammonia, so next time
I'll leave it in longer.
I didn't pull any of the keytops off, not sure if
they just pop off (probably).
My TIPPC came with several of the key tops broken
off, and was led to believe this happened in transit
(yeah likely). Luckily I have 2 keyboards that
although resemble a desktop TI PC's to a large extent,
they have a different connector (like a header
connector - anyone have a clue what they're for?
Probably a terminal I would imagine). So I aim to
unsolder the offending "pots" and solder new ones in,
repleat with the correct key top.
