This razzles a bell for me, I wonder if this is related to the BASIC computer we had at school, 1980-ish, we called it the "Alpha" and it had a drum memory that had to be de-megnetized(?) every once in a while and we had to backup our programs on punched tape. There was only one CRT and 2-3 Non CRT TTY terminals, very much like a electric type writer. It had a CAI-BASIC according to some programmers ref card I found in a box with stuff from this time in the cellar. There are also some paper listenings of small programs I wrote and a version of "startrek" I printed out for some reason.
