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.
