Vintage computers aren't your typical collector's item, but some of the earliest PCs from the 1970s and 80s are already starting to command big bucks in working condition. This is particularly true of models that preceded the volume production IBM PCs and Apple Macintoshes, such as MITs Altair 8800 (1975) and 680 (1976) kit computers, Apple IIs with low serial numbers (1977), early Commodore 64’s (1982) and Apple Lisas (1983).

Aside from the above, there are plenty of vintage computer names to collect, including Compaq, Kaypro, Amiga, Sinclair, Franklin, Xerox, Digital Equipment, Atari, Heathkit, Texas Instruments, and Silicon Graphics. With vintage computers, displayability is key, so make sure you get all the accessories, software, manuals and power cords you'll need to run your vintage machine.

Also, keep your eye out for vintage computer-related paper items and ephemera. Some early magazines, like the famous January 1975 Popular Electronics issue featuring the Altair 8800, can fetch over $100.
