CHM has been my favorite to visit every time I'm in the area. I do wish they would have more modern stuff though. Especially the period between 90s to 2010s. There are some parts (first iPhone, Palm Pilot), but I wish they would continue because the internet age has been incredibly important.

Not a computer museum but I have a soft spot for the Connections Museum in Seattle, WA https://en.m.wikipedia.org/wiki/Connections_Museum
