So, yea for dfm - it started on the 990's and of course is very similar to TI-Writer/Editor Assembler editors.

I think you have the heritage of later versions of dfm figured out, Gleen took it and made it available for TI and later HPUX systems along with ISAMATION.

Larry Kroeker made a PC version available, at one point, I think Larry had a proto-windows version going.

I also think Larry has passed.

I did see an obit notice for a Larry Kroeker in McKinney, TX ca. 2011. Didn't see the full obit.

In the past, TI was very pragmatic about licensing. So I imagine it was as easy as say Larry talking to someone in management along the lines of:

   Larry: Do you have any plans of selling dfm in the PC market.

   TI: No

   Larry: Do you mind if I do?

   TI: No, but we get 2% royalties and maintain our original copyright.

Tallies with what I've heard. Still want to nail down what ISSS was, but that's going on the stack for now. I'll be interested to follow Robert's take on DF-[SHOW,EDIT]  for modern OSes. He may be interested to know that 990 dfm supported tape files and encryption. I don't know if any of the DOS versions did. He may want to take a look at Midnight Commander, too, which bears a lot of DOS influences, possibly DF-EDIT and SHOW included. Looks like maybe he's following up an elder relation's project here? Wish him well with it, and maybe it will bear fruit with a new DOS or Windows version as well. Lot of people building retro DOS boxes these days.
