Hey all.

Did some searching, and haven't been able to come up with an answer on this one. Me and a buddy at work have been hashing this one out for a bit, and I feel like we're missing something.

Now, I'll preface this by saying I've never had the pleasure of diving into the guts of a Vector display. Only raster monitors.

On a Monochrome Vector, the monitor's deflection is directly driven by the deflection board, along with the Z-Axis (Intensity), right?

On a raster, you've got the Horizontal and Vertical Scan Oscillators hooked up in line with everything else.

Is there any technical reason you couldn't use a B&W "Raster" display, say out of a TV or some such, and disconnect the Horizontal and Vertical oscillators, then hook the H/V Amplifier Inputs to the appropriate deflection controls on the deflection board?

As a side note, if you drove all of the color guns in a Color Raster from the same signal line (Creating White), wouldn't this be similar in appearance? (Similar, not the same! I know the Shadow Mask gets in the way.)

Thanks for fielding my questions.
 
Looks like he hand wound his yoke.. On a new monitor? I must be missing some details on the differences between Raster and Vector yokes. Inductive differences?

Otherwise it looks like he did what I thought you'd do; drive the H/V via the deflection board.
 
Yeah, that would be really difficult to pull off because the yoke isn't designed for that kind of slew speed. To get X/Y monitor slew speeds with a raster yoke, you'd need a really high gain amplifier, and probably a lot of correction circuitry (and probably a new yoke, because the old one would fry immediately :p ). The other way would probably be much easier (Raster using an X/Y monitor).
