As a kind of prelude to IBM, it should be noted that the Computer Services Division (CSD) was stripped of its responsibilities for doing administrative programming around 1981. All of the programmers were moved from the Ivinson building to Old Main, and were placed under the vice president for finance. CSD was left in charge of merely operating the administrative systems, overseeing maintenance, and programming/managing the operating system. The new group was called IDM (Institutional Data Management), and later renamed OAS (Office of Administrative Systems). This seemed a largely political move, a power grab or turf war so to speak. The administrative users were not pleased and felt they could do better if the programmers were part of their own structure. By around 1989, with a new director, OAS was recaptured and assimilated back into CSD.
There were old stories about IBM using dirty tricks to make sales at UW, and there was a great deal of resentment and dislike of IBM as a result. The arrival of the 4361 was therefore a disappointment but something that couldn't be stopped.
The 3081 had been purchased, not leased, and when it was retired it had less resale value than its shipping costs. Four of us purchased it as scrap and tore it down to bare metal, keeping some of the more interesting bits and giving the rest to a friendly recycler. The main souvenirs were the Thermal Conduction Modules (TCMs) which, when first manufactured, cost around $50,000 to $100,000 each. How many of you have a $100,000 paper weight?
Two good articles describing TCMs are in the IBM Journal of Research and Development, V26 no. 1, January 1982.
