My first encounter with computer graphics being used in a protein crystallography laboratory was in 1984 when a class I was in was shown an Evans and Sutherland (E&S) Picture System 2, or PS2 for short. The display was black-and-white but still it was quite impressive and was one of the things that led me to go into the field as a PhD student. Thus, a year later I had the opportunity to use a colour E&S system, which was appreciably better, for my own research project. It was controlled by a PDP-11/60 which had 128k of RAM while the PS2 itself had 64k of RAM[1].

Colour graphic terminals were also available. This photograph is reproduced with the permission of the Museum Waalsdorp, The Hague, Netherlands.
A few years after that, as a post-doc, I had the privilege of being given an RK07 disk cartridge which cost the department the best part of £1000 and allowed me to store almost 30 MB of my own data, rather than begging, borrowing or stealing space on other peoples' disks. These cartridges had to be placed very carefully in one of the PDP-11 disk drives, each of which was about the size of a domestic washing machine, if not larger. The computer alone cost several times the average UK house price, as did the PS2. Although the technology was brand new in its day, these costs do seem rather excessive for a box or two of electronics. I am sure that part of the profit model was to make these machines significantly, but not massively, cheaper than employing the legions of accountants and draftsmen which they would come to replace in the commercial sector.
