The scopewriter isn?t really a vector display. It generated a sideways ( 90
degree ) raster that scans from bottom to top of the display by virtue of a
ramp voltage. It creates ASCII characters from a character generator ROM
that turns the ramp on and off without using Z axis. It is a kind of return
to zero ( voltage ) display when the modulator (character generator ) says
to turn off the transmission gate ( 4066 ) to blank that section of the
character. Very cool idea for it?s time. Mine is somewhere in storage hell.

I don't have one of these myself yet but I should buy one to make use of my
Tek X-Y monitor.
