It might be difficult to build something equivalent to the AVR Scope Clock
from scratch for less than $30 by the time you're
all done, if this
hardware is suitable for your needs.

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

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.

Is that anything similar to the scope display built into the SYM-1 board? I
have looked at that in the manual in the past but have never tried hooking
a SYM-1 up to a scope. Has anyone on the list experimented with that?

I have an older version of the hardware - binding posts for scope
probes, no on-board amplifier to directly drive scope inputs via BNC
cables, but otherwise similar. I had fun putting it together in 2008.
