Looking for

Last known dates of operations of some machines - did any make it to the 21st century in actual use (as opposed to museum exhibits)?
The University of Manitoba had been given a network analyzer some time in the 1970s, but I doubt it was ever put into operating condition again - the bits filled one of our classrooms, as I recall, but I never took any interest in it then.
There must have been analyzers in Europe but there's not much showing up under Google. One British analyzer has a paper describing it on IEEE, but as always, no matter how many societies you pay for, the paper you want is never in your subscription.
A photo would be great - many of the papers have pictures, but can't use those photos.
Probably could have a little more description on how a problem was set up on an analyzer.
Some discussion on the influence analyzer methods had on early digital computer methods. --Wtshymanski (talk) 19:17, 8 February 2013 (UTC)[reply]
GE machines all 480 Hz, Westinghouse all 440 Hz? Iowa State was 10 kHz and their own make. The AEI machine was 500 Hz - did they build their own? What of France and Russia? --Wtshymanski (talk) 05:03, 10 February 2013 (UTC)[reply]
~~Biography for Hazen, who had a long career, WWII work, etc. - ca. 1901- ca. 1978 is about all I've got for dates.~~
"Transient network analyzer" vs. regular kind - for impulses, lighting surges, switching surges. How did these differ from the systems used for load flow and short circuit? --Wtshymanski (talk) 05:36, 10 February 2013 (UTC)[reply]
Hydro Quebec built an analog network analyzer for their IREQ Power System Simulation Laboratory in 1973 - was this the same sort of machine for doing load flow, etc. or was it just for transients? Still looking for a detailed description of this one. It was energized at either 50 or 60 Hz, according to a 1994 IEEE "Canadian review" article. --Wtshymanski (talk) 22:22, 7 February 2014 (UTC)[reply]
