IBM control program of operating system 360

Full film IBM B&W film introducing OS/360. The title is IBM CONTROL PROGRAM OF OPERATING SYSTEM/360. IBM's System/360 mainframe turns 50 soon and since YouTube now allows much larger uploads here is the complete introduction to OS/360. Preserved thanks to Michael Stack http://kcats.org Wonderful historical material but its hard to watch the whole thing even with beer and popcorn. Enjoy my geeky mainframe friends!
