I just found these on SVT ?ppet Arkiv (Open Archive).
Aside from the fact that they are fascinating time documents (cloths,
haircuts, way of speaking), these are a little bit of interest to this
community. I guess that since computers were not very commonplace at that
time, SVT really liked to emphasize how modern they were to actually use
computers.
In the 1968 they show a guy that explains that the terminal is connected to
a (IBM) 360/40 computer. Later on the actual machine is shown.
Apparently they replaced IBM by DEC in 1976 since they are showing off two
PDP-11/40 this time.
And in 1982 they put the machines almost on the scene.
