I don't know how long the company was already running this diffractometer, but adding stepping motors was not a commercial solution. Perhaps this was done in cooperation with the research centre in Munich (Germany) where these gonometers were developed.
Later I used this goniometer for my own diploma thesis.

I think this answers my question. [By automated I mean simply producing digital data, in x y pairs.] In 1980, in Bob Snyderâs lab we had an automated Philips; the mounting of the stepper motor was home-brew, but the electronics consisted of out-of-the-box Canberra products. So I presumed that this not, by any means, the first of the automated lab machines, and was curious as to when first one was commissioned. Never knew the Type F was sold by Siemens as automated? What year was this? Googling âautomated siemens type fâ yields no joy.

Neutron diffractometers were automatic well before x-ray diffractometers, and were also first for position sensitive detectors (PSDs) and of course Rietveld refinement. Paper tape control was introduced in the 1950's, computers in the early 1960's and PSD's in the early 1970's. X-rays followed after about 10 years. From memory only. It can't be difficult to Google this.
