good lord! if that is for real it is truly amazing in 1963!

apparently Autocad has kept its GUI at the same level till today (perhaps for nostalgic reasons?)

... yep ADESK can proudly say - established in 1963 still keeping up to standards of the Moon-landing decade!

but now seriously. it is impressive for that time.

Brings back memories for all of us old f*rts who are here...

The flickering screens could really drive you crazy. I think that Alan Kay mis-spoke on a couple of things. One was where he said that there were not graphics displays back then. That is not true ... it is just that graphics displays were vector displays like that shown for many years, where the software drove the magnets that deflected the electron beam to draw the vectors. The more vectors, the more flickering since the phosphor on the screen would lose the image before the beam came around again to refresh. Software had to actually optimize the order of the 'painting' of the vectors to boost the number of vectors that could be seen before flickering started. Later units could paint faster and used faster phosphors until raster (TV-like full top to bottom beam scan) CRT's took over from vector units entirely and flickering was replaced by pixillation...although the early raster years saw both (flickering and pixillation)...
