More to the
point, though, rasterising the vector screen is exactly what
those old Tek printers did! They scanned the surface of the tube in a
raster fashion, and read out what they found there. I don't know how
well the analogue circuitry preserved the grey scale - my 4631 hasn't
worked since I got it - but done well, this could do pretty good
staircase elimination.
There is no grayscale in a storage tube monitor. There's charge
stored on the tube, or there isn't.
