He coordinated the "systems lab" and I think was central to acquiring the 7094 II from surplus. The last paper (which you can actually download unlike Purdue who seems to have locked their papers up) hints at why that might have been done. UW had a Univac 1108 and two B5500's when I started (the second loaned because Burroughs was late delivering the B8500 - and then lied to UW when the faculty paid a visit - by lashing up a pair of B6500's, according to one prof. I had who was there.) The 1108 and B5500's were replaced by a Univac 1110 before I graduated in 1975. There was also a CDC 3600 and a CDC 1604. The CDC 3600 was damaged in the infamous Sterling Hall bombing, but I think the 1604 came out fine. I expect those were both gone by 1975. The system lab had a PDP-11/20 and a Datacraft 6024, then after UNIX showed up (V6 and then V7) got a PDP-11/45 and a PDP-11/40 that was not used for UNIX, and then a PDP-11/70 for UNIX for the CS department shortly after I graduated and left. The 7094 II and the Oscar Mayer 1410 were not used for anything serious and only lasted a couple of years - there were not even any peripherals for them. I think Prof. Desautels intended they be used for entry level instructional classes in FORTRAN and COBOL, maybe (see above). Engineering had a couple of IBM 1620's (one with a disk) that became disused when they obtained a Datacraft 6024 around 1970, I think. The electrical engineering department had a PDP-11/20 almost identical to the one the the CS dept. had that I did some independent study on. The School of Business, where I worked as student help / grad project assistant had an IBM 1410 that had been used by the UW Registrar. When the administration consolidated, they obtained some model of IBM S/360. There was an old old IBM 7094 with oil core (or maybe even a 7090, I don't recall) on the 9th floor of the Chemistry building used by one particular researcher. It had Potter peripherals. At one point it failed pretty badly, and three of us went over to see if we could figure out the problem. They ended up calling in a couple of guys from Purdue to help figure it out. The Social Science Research Institute had a S/360 (a model 30 or 50, I think), as well, right across the street from the School of Business. To try and get their arms around instructional computing, the UW computing committee (which somehow ended up with an acronym something like acc-acc) commissioned a DEC PDP-11/70 for students to use, replacing the Business School 1410 and some other smaller systems. It was a disaster - it just couldn't keep up. We were able to play with it because it was core-resident - didn't need any peripherals to run once it got loaded (see the above third paper.)
