Tim says:
"Yeah, I don't know if I'd want to do that with the existing flyback, if even the yoke. Might be possible to use newer parts removed from a high resolution monitor (nice if the yoke fits!). To make things easier, I would put in triggered oscillators (instead of free-running locked oscillators that don't have as much range) and current amplifiers to drive the yokes. HV is a seperate supply.
It would be a bit of a mess, but easier to work on than a cheapified TV circuit, and also lets you use it as a slow X-Y display. (Add a high speed sampler circuit and you can make a 1GHz+ sampling oscilloscope.)

I had a feeling that's what he'd say. It does make more sense to use newer technology, instead of hacking the original stuff. Now let's see someone do it!
