Your memory is fine - TECO used "er" to open the input file and "eb" to open it read/write. I used TECO for many years, and even wrote my own implementation in C, and later I was responsible for the DECUS TECO library, then later still for the de-facto TECO archive, which I recently put on SourceForge, at

Kinda weird that I started this thread on the TextMate list and ended up discussing TECO...

Not really ... I think a read-only mode should be a standard feature of any serious editor. Just consider past examples e.g. vi, Emacs, Edt, possibly even TECO (but my memory fails me here; digression: TECO is probably the most powerful/dangerous/sparse/delightfully cryptic text (character) editor that's ever existed; Emacs used to be written in it).
