I am looking for resources - websites, books, etc... - that have information on antiquated computers. Specifically those from around 1975 onwards. Maybe with clock speeds of about 5MHz+. I don't need specific information - something like a history would be ideal. I have some knowledge of processor architecture and assembly programming, so I would be comfortable reading somewhat technical stuff. I'm mostly interested in microcomputers, but I'm looking for inspiration, so don't let that limit you.
