I've searched for many different things over the last few years.

I was hoping that people may have had old Sixel or ReGIS graphics in 
their various archives that they might be willing to share.

Thank you for the links.  I think I've seen > 90% of those pages in the 
last few years.  I've extracted a number of things from them too.

Agreed.

Yep.

I'm aware of and have looked at some of the documentation from a 100 
foot view.  I'm trying to keep from falling in too far, yet.

All of my testing has been done via XTerm.  I've had my decTerminalID 
set to vt340 (in ~/.Xdefaults) for ~18 months to test various things.

I've gotten 256 color Sixel support working quite well in XTerm.  I can 
even watch animated .gif files by running them through img2sixe.  :-)

I need to get access to a good Usenet archive of this newsgroup.  My 
news servers (that I run) only have history going back to when I stood 
them up about three months ago.

I need to use DDG more.  Google routinely has me cussing at for one 
reason or another.

Thank you fro the very detailed response Stephen.  I do appreciate it.
