I saw an IBM PS/2 Model 55SX at an estate sale this past weekend. It took me back to my first non-food service, non-retail job, doing desktop support at Mizzou.
Well, as a precursor to doing desktop support, they tried me out just building and tearing down machines. I worked out of Room 11, which was at the time a dingy, dark, musty place. But they pay was good and it meant I got to spend my time between classes taking computers apart all day, and that was nice.
My first assignment was to build IBM PC 330 and PC 350 computers to sit on professors’ desks. These were 50 MHz 486DX2s. They were a bit outmoded by then, but they were a lot better than what they were replacing, which was, in most cases, a PS/2 Model 55SX, which was a 386SX running at either 16 or 25 MHz. My second assignment was to disassemble those Model 55SXs, reverting them back to their factory configuration, and sort out all of the add-ins so we could use them to upgrade other machines, and then, sell whatever was left as surplus.
