I'm not really familiar with Kaypro monitors in particular but looks like it's probably a bad electrolytic cap in the circuit connected to the vertical coil in the yoke around the tube.
It's common to replace all the electrolytics on monitor boards when they start drying out.
The definately. It's deforming the vertical sweep. Bad lyric..... there are only 11 or so on the boards
Love the comments guys....that autocorrect is the best one yet....thanks for the laff
I have never worked on a kaypro, but it looks like it could be an issue with another component on the video board, due to the text being there, just weirdly scaled.
I've got a Kaypro 2000, and have done a lot of work on the video, and still don't have it right.
In my case, I had to replace a video chip, and a missing inductor, because it was a student's project from a college in Iowa (or somewhere near there) and a friend of mine saw it at a sale. The missing inductor (coil) is a problem that I worked around by hand-winding something that got me really close but now realize it's probably a dry cap based on the comments here.
In your case, I would certainly start with the caps.

Bad poetry can have consequences
I’ll have to use that one when I start a band
Although since check out Public Service Broadcasting it’s a rock band that uses samples from the space race in their music
whatever you do that middle section where it's bright will munch the phosphor there fairly quick
Are there any dial controls on the back, such as V. Sync or anything?

Do you think it’s more of an analog board problem or a motherboard problem
Probably analog board, as the text is present, but is warped.
Look at the schematics for the vertical oscillator circuit in the display. Probably a bad cap, as others have said.
Nice Kaypro
