There's suposed to be a pretty good computer museum in San Jose, CA but I never been to it.
The Apple IIGS was a cool little computer with a mouse and networking capability. They could be networked together with Apple Talk and simple phone net connectors. I used one of the early Macs as my classroom server so the kids never had to go back to the same computer to retreive their work. That led to my first Linux server that could talk to both PCs and Macs.
