how can I get a vector game to play on an oscilloscope? I tried for a half hour to get it to sync up with my tempest, but it kept scrolling the image, I could never get it to hold.
 
Are you sure the PCB is in working shape? I have an older cheap OSC and it locked into the game right away without any scrolling.
 
It's going to look "wrong" without Z/trigger hooked up too. If it looks like the game's mostly there but there's a lot of extra lines, mostly coming from/to the center of the screen, that's what you're seeing.
 
It looked as if it was scrolling, like I couldn't get a steady image, not that it was all connected, similar to when you don't have vertical hold set right on a raster monitor.
 
The time doesn't have an effect when displaying a vector image. You need to make sure your scope is in XY mode.
 
For the other side of the coin: A friend of mine used to make 3 channel O-scopes. He made them from 25" Ampliphone monitors pulled from converted Star Wars cockpits. This was back in the mid 90s. He sold the modified monitors to colleges for electronics and science classes.
