Somewhere around 1980, I heard about PDP-11 systems that had side-panels designed by Corita Kent (a nun and pop artist, who amongst other things designed a stamp for the US post office, and gas storage tanks along the Boston southeast expressway). And in fact there's a picture of an installation at the Corita Kent web site. It looks like a PDP-11/23 to me.
At the time I first heard of these, I think they were cynically described as "Gordon Bell's contribution to the arts". The photo accords with my memory: computer with side-panels, desk side-panel(s), wall-hanging.
But my question is: were any of these actually sold? How many?
