Chips Etc.
Computers are upgraded more frequently than fashion, which means there’s a lot of obsolete hardware out there for collectors. As their site’s name implies, the folks at Chips Etc. are particularly interested in the computer chips made by companies like Intel and AMD, but they also have photographs and information about vacuum tubes used in early IBMs, transistors made by Bell Labs, and even promotional items such as keychains and medallions given to employees at Apple and Cray.
