This category is about collecting CPUs (also known as processors or microprocessors) from various computer systems and devices from a variety of years, ranging from rare early vintage models to more modern types (including prototypes and engineering samples). Included in this category is information about the acquisition, display, identification, and conservation of CPUs.
Acceptable sites should contain original content pertaining to the acquisition, display, identification, and conservation of CPUs/processors that would be useful or of interest to collectors. For quick review please search through the subcategories to find the correct placement of your site.

All sites, which offer products and collectibles for sale on line and off line, should be submitted to Shopping/Antiques_and_Collectibles. Commercial sites will not be accepted in this category.
