I lived for awhile in North Kingston RI and I absolutely loved the Rhode Island Computer Mueseum. It was usually staffed by older gentlemen, who would absolutely love to go into any topic related to computers they knew about. One of my now core memories is playing the original space wars on a working (only 8 remaining if i remember correctly) pdp 12 with one of my friends in elementary school.
RICM has one of those PDP-12s. And RCS/RI also has one! Two of these very rare machines, both in working condition, are located within a few miles of each other.
