Hypertext before the World Wide Web?
When I was a resident back in 1988, I wrote a hypertext authoring system for MS-DOS called HYTEXT. That was a time of 80 x 24 line monochrome displays and command line interfaces. I knew nothing about networks at the time, but I did create a mark-up language that anticipates HTML in many ways. I recently came across a paper copy of my original documentation and thought it would be a good idea to reproduce a few pages here for posterity. The original program and documentation are on 5.25 inch floppy discs that I have no way to read. But I googled it and found my 22 year old file online!
