As a kid who grew up in Massachusetts in the 80s and 90s, I'd love to go back in time and experience the competing tech that was being built in my back yard before the west coast totally won out. I had friends whose parents worked for both DEC and Wang Laboratories, and had those companies' gear in their homes. At the time I only cared about what games you could put on or write for them, but it would be awesome to poke around on them again as an adult.
