Subject: [sdiy] tiny oscilloscope from camcorder CRT viewfinder

I have a tiny little B&W CRT-based viewfinder from an older, but not ancient

8mm camcorder.

I thought it might be cool to put it as an oscilloscope which could fit in a

regular synth-module sized enclosure.

I've read about old article making a scope out of a TV, but I don't think 
that'd apply here so much.

I thought maybe some circuits to process the signal and to drive the coils.

I can't tell if this thing takes NTSC composite video or if the small 
circuit board is just a raster-scanner or whatever it's called.

Anyone ever seen anything like this?
