[SIGCIS-Members] UCLA's 1948 Mechanical Computer

[PeterEckstein at comcast.net]

The presentation implies that this Differential Analyzer came to UCLA a few years earlier.  Before WW II there were DAs at MIT and the Aberdeen Proving Ground, but does anyone know how this one came to or was built at UCLA?  I've never seen a video of a DA in operation, but this one seems more smoothly mechanized than those shown in still photos, certainly those of Bush with one at MIT. J. Presper Eckert worked under Professor Cornelius Weygandt to make the DA at Penn more electronic (before he switched over to work on the all-electronic ENIAC) but this UCLA machine seems to still be entirely electromechanical.  Can anyone confirm or deny my suppositions or otherwise clarify the history of this machine?
