Re: teaching computing to kiddies.
Ahh! OS/2. I had OS/2 for Windows - it came free from somewhere and, when installed on a computer with MS-DOS 5 and Windows 3, replaced it with OS/2. I had to wipe my computer and start again to return to DOS and Windows, which I inevitably had to do when it turned out that some of my more demanding software wouldn't run on 'a better DOS than DOS and a better Windows than Windows'.
