I'm looking for any useful TECO macros in the public domain.  Also any
TECO manuals, preferably in machine-readable form.  If anyone happens to
know the answers to any of the following questions, I'd sure appreciate
hearing them.

Is there a small version of EMACS TECO macro suitable for implementation
on a micro with V29 TECO?  (Specifically, I have a V29 TECO implementation
on a 6502 based micro).

I've seen two screen editor macros for TECO on a RSTS system; VTEDIT (for
VT100's), and VT52 (a small editor for VT52's).  Are these considered in
the public domain?  Are they DEC copyrighted?  Or what?

Is there a TECO specification other than the DEC TECO manuals?  There was
an active DEC TECO SIG at one point.  I understand a newsletter was
published with discussions of extensions, and possibly specifications
for V29 and later.  Anyone know where I might aquire backissues of these
newsletters?

I'm hoping to bring my 6502 TECO to market in the future, and have no
great desire to write a manual from scratch.  Any available software
(screen editor macros, text justification, etc.) that would help make
TECO successful would be much appreciated.  There seems to be a lot
of interest in TECO still, and hopefully bringing it to micros in
affordable form will keep interest in TECO alive.

Much thanks in advance,
