I havent seen those wince the mid 1970's!!!!!
Back when I forst worked on the PDP-8, the school district was using it for
automatic grading of multiple choice exams [among other things]. The system
had a flat scanner that would process a page that had been marked with a #2
pencil. I forget the dimensions and other details (it has been nearly 30
years), but I seem to remember that the sheet was 8.5x11. Was this a
"standard" type of peripheral????
