I finally got a Kaypro II. Unfortunately, it appears to have a display problem. When I turn it on, I see the "Please place your diskette into drive A", but it's repeated on 4 different lines and it's flickering. It looks as if there's a vertical hold problem or something.

Has anybody seen this and/or know how to fix it? I'm hoping there's some kind of simple adjustment I can make.

I fixed it!! I did what only an insane desperate retro-freak would do: I fiddled with some unlabelled adjustment wheels on the display board while the unit was on.

Now it's perfect. (...and it was worth the risk of electrocution)

After the adjustment, you may see loss of sync when the unit is cold and sync gained when the unit warms up (or vice versa). If so, further adjustment is required to find the middle ground.

Thanks. I'll watch out for that.
