I was at the Living Computer Museum again last weekend. No surprise for people who read this blog. It is one of my favorite places to visit in Seattle. Every time I go there, I find something new that captures my imagination or educates me. Today I would like to talk about another way of experiencing this wonderful facility, as a learning library. It all started when I stumbled across this PDP 11/70 Processor Handbook that someone had left near one of the PDP machines.
