Maybe I misled a few, I have all those old media but I have created directories on my hard disk an copy all the files to them and then I create DVD's of all of them. I have dos 1.0, .1 and all the way up to 6.22 as images so that I can get to them if necessary.
FWIW: a friend of mine is a dentist and has an office management system written in compiled basic which requires extended memory. His old dos machine went south and he was in panic mode. I just put a new(old) hard disk in his 386 machine, formatted with the dos disk and copied all of his executables and data from his old disk. I had to really jump into the back of my memory on how to setup himem.sys and that in the config.sys. emm386 was interesting to get involved again. But bottom line. He was thrilled and it ran great and my teeth are now cleaner than they have ever been.
