Hi Dan (& others).
I'm an occasional lurker these days. I still have SlickEdit installed, though not using it much. :-(
Fascinating to hear about those old versions. I went through the IBM Personal Editor -> E -> E2 -> E3 -> EPM route to SlickEdit myself, if I remember right and if anyone else remembers those. Personal Editor was an IBM product for the original PC. (by Jim Wylie? How is my memory?) The 'E' line of editors were "internal use" at IBM, developed by Clark Maurer, who started SlickEdit. All text mode until EPM (E for OS/2 Presentation Manager).
Sadly, when I moved house a little over a year ago, the 3.5" floppies went in the bin. I think there were some of those old 'E' editors on them, among some other early IBM treasures.
