			===PDP-2 ½===

			Doug Jones' [https://homepage.cs.uiowa.edu/~jones/pdp8/faqs/ PDP-8 FAQ] says "''There is also a story about the PDP-2 1/2, built by Ed Rawson of the American Science Institute out of surplus modules that were originally used in the prototype PDP-2.''" Searching for clues we find this alt.sys.pdp10 message by Max ben-Aaron dated February 1997:

			<blockquote>In the late 60's & early 70's I worked for a company (Medidata, later Searle Medidata) which started life as a not-for-profit spin-off from Lincoln Lab. (as I have heard), called American Science Institute. The chief engineer, Ed Rawson was a friend of Dec's Olsen and he managed to get hold of the modules used for the prototype PDP-2 which never reached the market. ASI used them to build their own machine (designed, I believe, by Chuck Corderman) which they called "Casino" and was sometimes jocularly referred to as a PDP-2 1/2. Casino was noteworthy for having, very early in trhe game, graphics capabilities. It also had some special terminals which had labels that cannot be repeated on this (family) newsgroup.</blockquote>

			Interestingly, this says there '''was''' a PDP-2 prototype, implying it was in fact designed to some degree.
