I watched invation of time with Tom Baker. It used the old set from deadly assassin . The tardis interior was a building with windows. Does anyone except this as the tardis.
It was brilliant for it's time (the 1970s). and the BBC had to make due with what they had, so, for that, yes it was acceptible. But, looking back, It was not very beleavable as what you would see as an alien time/space capsule.
If you have seen the episode "Shada", the proffesor's living space at the college was actually a tardis. It had just blended in as part of the College building.
The BBC is famous for recycling props. By today's standards, it looks hokey. What I liked about the episode was the feel of how big the inside of the tardis is. Other episodes showed walking in corridors, but this one had running up and down stairs. It showed that there's more to the tardis than we imagined.
Maybe away from the console, the tardis takes on more of the Doctor's personality.
