OT: convert TV/monitor to XYZ monitor

[Per Mattsson]

Leaving semilurkng mode for awhile and I know this is kind of OT but this
is were the knowledge is.

I've done some "oscillographics" bye running to signals from various
modules into the X and Y of my oscillocope. Synched oscillators and
ringmodulators can  do wonders.
Now I want ot expand this to a larger screen and also make it into a XYZ
setup and my  eyes fell on a computermonitor I have left over.

Does anyone know of any online schematics or an articel on how to convert a
teve or monitor to a XYZ-monitor?
I have some old Elektor articles from 1978 were you  draw oscilloscope like
curves onto a normal videomonitor but it didn't provide X-control which is
crucial here.
The straight CV into  XYZ setup is very lowlevel approach to draw lines
onto a CRT so maybe I heading the wrong way? Is it perhaps better to try to
find some modules that draws these line in a normal color-tv video signal.
It would allow for expanded mixing and interacting with other video
equipment. But that would quite possibly also include microprocessing,
framebuffering etc and I'm kind into the analogue thing right now.

http://www.AudioVisualizers.com/ has a lot of info, articles and a few
suggestions on schematics but none of it is what I need right now.

any hints, suggestions, books, articles? I'm all ears.
