I have been collecting vintage computers off and on for about 9 years now, also like vintage radio's and audio equipment. It was at the Huntsville hamfest that I acquired my oldest " also broken" computer, a TRS 80 Model I. My most reliable vintage sytem is a Tandy HX 1000, and I used to use my TRS 80 model 100 to take notes with in high school. Hope to get the Model I working, but that is another topic.
