When I wanted to save the 3D graphics program I had developed on the IBM360/370 I audio recorded with a phone tap magnetic pickup the 300 baud connection to my terminal while listing the program to the screen. All I have to do now is play back the tape to an acoustic coupled modem . . . Oops!
I still have all my punched cards from the 70's of the programs I wrote in college saved in one long original cardboard box the cards came in.
How about them 8 inch floppy disks with hard sectoring? Got them still and a reel of 9 track tape too! I even have a suite case PC somewhere on a shelf here in my office . . . Osborne computer. My Televideo dual floppy CP/M computer with the green screen and ergonomic keyboard (yeah we're talking palm rests) still runs on the back shelf. Now that's a blast from 1980!
