I really am interested in the golden years of mainframe computing - the 1960s and 1970s. At this time, you'll recall that the major manufacturers were called Snow White and the Seven Dwarves, referring to IBM and Burroughs, Univac, NCR, Control Data, Honeywell, GE, and RCA.
Getting information on these original, old mainframes is relatively difficult. What I'm interested in knowing is what were the merits of the various mainframe families from these early pioneering companies? What did these companies compete on? Architecture? Serivce? Support? Price?
In the end, I'd like to deepen my understanding of the unique and significant architectures.
For example, it appears that the two RCA families - the Spectra and the RCA Series - were simply IBM 360 and 370 compatibles. Not interesting.
I can't find much about NCR and Honeywell (prior to the acquisition of GE's computer business)
Wikipedia has some good info on the GE-635, which seems to indicate they're only slightly interesting from the standpoint of being an early SMP machine and having programmable I/O controllers. But I'm wondering if the GE machines really were significant.
Control Data seems to have some good information available about their 6600 series - the first supercomputer. I'd put them in the interesting/significant camp.
Univac is company that arguable started the industry, so I'd certainly call them intersesting & significant.
Burroughs seemed to have a good reputatation and a unique stack-based design. Their OS (the "Master Control Program") gets positive comments, so I'd guess that was interesting & significant.
So, from the list, it seems like CDC, Univac, and Burroughs may be the most interesting from the group?
