Hola all,
This is barely worthy of cbm-hackers, but for what it's worth, I had my
C128D keyboard open to fix up my barely-functional cursor left-right and
right-shift keys. The plastic frame holding the keys is attached to the
PCB and metal backplate via 21 tiny screws, which screw into small plastic
posts on the upper piece. A close look showed that most of these posts
have cracks in them, and hence are no longer holding the screws securely
(there are also some stress cracks/creases beginning on the upper plastic
key holder).
I believe that what's been happening is that when I press shift or
cursor-lr, it actually pushes the upper part away from the PCB instead of
making good contact -- the only way to make these keys work has been to
push down extremely hard.
My solution here was to drill a hole through the metal/pcb/keyboard holder
near the space bar and put a small 4-40 bolt+nut through, to hold the
assembly together (there are several raised plastic surfaces near the
space bar, giving a more secure/even point of contact). Time will tell if
this is effective; so far so good.
I also took a look at the plastic enclosure for the keyboard and sure
enough, cracks were forming in the much thicker plastic posts that receive
the screws.
For what it's worth...
