Do you have a picture?? Or is it the
one in the post on 2/15 at 12:31 ?
I have repaired / modified / designed printed circuits for around
40-50 years.? Pads on any board I have ever seen, or touched are
copper.? Pads made as option jumpers might have solder on them,
but the solder is on top of the copper.? The copper is bonded to
the fiberglass board.? Depending on the board quality, you do have
to work fast.? Some of the lower quality boards the bonding isn't
good, and the adhesive lets go.? Sometimes, it's easier to use a
small piece of fine wire to make the jumper, as opposed to
blobbing on enough solder to get it to bridge.?
I have a couple of K1000 keyboards, and one of the rack mount
version of the same.? I have worked on them in the past, never
noticed anything unusual about them.?

To Dynahoe Dave:
Most of the soldering tutorials tell you to how to solder solder
wire to metals of a much higher melting point. In the Kurzweil
1000, the solder pads are made of solder and can be melted just as
easily as the solder wire, that's why I was confused. Any thoughts
on this?
What should I tell the computer/electronics center?
