Ran across an incredibly interesting site the other day: Guidebook, the graphical user interface gallery. It’s basically a collection of info and detailed screenshots that effectively take you on a tour of various GUI’s that have existed over the last 20 years or so. It’s a great find and browsing it is time well spent for those who may not have had the opportunity to spend time with some of these OS’s and their interfaces which all, for their part, contributed to the current look and feel of the interfaces which are used by OS’s today. And strictly speaking, it’s not all graphical interfaces, as there are plenty of screenshots of various systems’ command prompts.
I have used some of the OS’s featured on this site, but not all. I have also spent time with GUI-based OS’s that are not represented by this site. But it’s a great collection and it really does take me back. Sweet nostalgia.
