That’s a big read and a great article. My first job, in London, as a young and ignorant engineer (I’m still two of those three things) I bought millions of £ worth of Sun hardware. Mostly pizza box SS20’s. I’ve always loved those machines. Very reliable, very heavy, and returned my employer an impressive ROI so I don’t get fired! I have a couple at home now, and I still have the IPX that was on my desk in 1994 I used to install, configure and maintain those machines. They were the days.
