BASIC environment ending with "run complete", and slashed 'O' characters?

I used to use some tty33’s in the 70s which were used to connect to an hp2000 timeshared system.  Those tty’s had the slash O and non-slash zero that you describe.  It may have been a common tty33 configuration.

Certainly it is not CDC practice; the only place I ever ran into this is with IBM, I always considered it an example of IBM doing things the weird way.  So it sounds like whoever bought those Teletype machines had them configured in that non-standard way for some reason.  Normal, as far as I know, was slashed digit zero.
