Spontaneous video! They're here! I just received an IBM 2821 Control Unit, straight from the System/360 era, plus an IBM 3880 Control Unit from the early 1980s. The 2821 controlled the famous 1403 Printer and 2540 Punch Card Reader, and the 3880 controlled the 3380 drive. The 3880 was very high on my wanted list! And of course, the cats have to help.
