[GreenKeys] Mod 28 KSR keyboard problem

[Jeff G]

Bob, look at the bit bars inside the unit if you can see them. Type
"RRYRYRY" on the keyboard, and you should see alternating bit bars being
set (so 1-3-5, and then 2-4). If one is "stuck" it'll cause what you're
seeing. When I worked on the ASR at the ship, I found the bar closest to me
was gummed up on a piece it was very close to and not moving. A little oil
loosened it up.
