Yeah, I knew the acronym was Tape Error COrrector, iirc. But the Bell 
Labs folks had to be pretty influenced by it since they used DEC equipment.

Because, of course. Was TECO only available on Tops 10? When I was at 
UCI, we had a DEC-10 which ran another OS and the editor we used was 
called the F-editor. But it's possible it was there and I just didn't 
know about it.

by Emacs.
