Yet another nice color brochure. https://dl.dropboxusercontent.com/u/96935524/Datormusuem/lab11.pdf
Has anyone seen a VR20 in real? Rather interesting to be able to do a red and green X/Y screen based on different energy levels. Someone care to explain how that works? If I read the fine print on the back correctly (and comparing with the others) I would guess that this brochure is from 1971.
