Alex, so you really think this might be the cause? The web-info I've read
on the Lisa suggests it's usually the pads that wear out causing
non-responsive keys and that these should be replaced. However what's odd
1. All the keys feel very firm, with no sign of the "mushiness" mentioned in
some of the info.
2. ALL the keys expect for one (in two keyboards) are not working AT ALL no
matter how hard you press. Yet the '4' in one and the '/' in another are
working fine and with no pressure needed at all? In the third keyboard NONE
It would be great if the problem wasn't the pads, but something more easy to
fix. It's hard to believe the pads could deteriorate 100% on all keys bar
one. And on that one they are fine? Anyone on the list had experience with
Lisa keyboards and could comment?
I'll be opening them up in the next day or so so I guess I'll soon see.
