We spent hours at the local one. Picked up lots of parts and gear when I suppose they would have rather us bought their relabeled Realistic stuff. In junior high helped the 5th grade teacher with his network of CoCo 2s that used a CoCo 3 as a "file server" via a rotary dial to download courseware through the cassette interface. I wrote a fraction math trainer in BASIC for him to use with the students. He was still using it when I was in high school.
It didn't push to the computers; we loaded the program from floppy to the CoCo 3 and then for each CoCo 2 manually executed a cassette load from the CoCo 3 via the rotary link, but it worked and was much cheaper than equipping each client with its own storage.
