Esentially the beam scanned back and forth and there was a detected at the bottom.  So George, would take the drive and sense wires off the microscope and connect them to the oscilloscope/camera combination.  He’d take one letter and stick it to the face of the oscilliscope.   We would then bring up the microscope software and tell it to scan a sample.   It would do so loading the image into the framebuffer.    We would then boot up MiniUnix and read the data out of the framebuffer and store it on an RK05 pack that we’d later take over to our main machine, the PDP-11/45 running a full up (hacked V6) UNIX.
