The Computer History Museum claims to house the largest and most significant collection of computing artifacts in the world (the "Heinz Nixdorf Museum", Paderborn, Germany, has more items on display but a far smaller total collectionHeinz Nixdorf Museum </ref>). This includes many rare or one-of-a-kind objects such as a Cray-1 supercomputer as well as a Cray-2, Cray-3, the Utah teapot, the 1969 Neiman Marcus Kitchen Computer, an Apple I, and an example of the first generation of Google's racks of custom-designed web servers. The collection comprises nearly 90,000 objects, photographs and films, as well as of cataloged documentation and several hundred gigabytes of software. <br>
