Probably just because of the title of the post, this made me think of Terse (terse.com).
Wow, I wonder if Jim Neil really is still selling it (it looks like he is). I wonder if it still comes on an 1.44MB diskette (http://terse.com/neildeal.htm#whatget) :-D
I never used it, nor saw it in use by anyone else. I just remember coming across it multiple times when looking at PC assembly language books and tools.
