As preparation for an eventual implementation, I'm writing a paper on the workings of the UC15, as determined from the schematics. I've answered the technical questions, but I'm left with a business question: was it a commercial success? The online census of 18b systems dates from '72, before

When I used a XVM 15 back in Syracuse, I was told that there were only about 15 (or some other small number) made. We did not use the 11 for much other then as a fancy print spooler. This was in the around '82. Rich As preparation for an eventual implementation, I'm writing a paper on the
