I had a TSR-80 from Radio Shack with audio tapes. If I remember correctly, you had to take out the program tape in order to save a document. I also had an Smith-Corona word processor that used little odd-sized hard diskettes that weren't even compatible with regular computers. I also have a box of 8" diskettes around here somewhere that my boss gave me because we were upgrading to the 5 1/4 drives. She was going to throw them away, so I took them. I was going to paint them and make art out of them, but never did. Funny! Melanie
