Hmm. Clem has a far richer recollection than I do. I don't recall Dan's version, but I defer to Clem.

I do have a vague recollection of a program called cr3 intended to mimic the tty driver thing. Perhaps that was Dan's version.

I note that my 4.1BSD manual more(1) says the author is "Eric Shienbrood, minor revisions by John Foderaro and Geoffrey Peck."

I also believe that is partially true and Mary Ann is actually correct in the provenance.

I think Eric arrived later than Dan (maybe a year later), but was also ex-MIT, and he too had used/seen --MORE-- on ITS as Dan had.  But I was under the impression Eric started over.  Then a few years after Eric, Geoff worked with Eric's sources to add a few features.  As for starting over/hacking on the program from Dan's original code base, it's hard to call that one, as  I recall that Dan's version was not much more than a hack on to cat(1). i.e. the original version was pretty simple, and I don't remember that it 'knew' about the type of terminal being used, get info from TERMCAP et al.
