Very interesting. The cartridges were probably NAB cartridges.
They are continuous loop, lubricated with graphite, with cue tones on the non-audio tracks. The graphite shed onto the playback head so you had to clean the heads every couple of shifts at a non-automated station. I would assume they had enough carts so that during a normal day the engineer would only have to clean them once or twice. The systems I'm familiar with were made by Gates (not Bill) in the early 70s. No computers at all in them.
