I remember, back in the beginning of the 80's, the new hospital in Johannesburg, had a little more advanced system. It was a rail system that ran from the desk areas up the wall, upside down on the ceiling, through the walls all over the place. Little boxes on wheels back and forth on this system all the time and when the patients came from one department to another, his file with the test results and so on would arrive for the doctors to consult. This was before the pc era. I remember, the track had a power rail and a linear gear and the box had it's own motor.
I can imagine before PLC's, the level of sophistication of such a system.
