Daguerreotype View Camera and Accessories, 1850
- Variable Condenser, Used by Alfred N. Goldsmith, 1920-1930 - Condensers (also known as capacitors) allow alternating electrical currents to pass while blocking direct currents. Condensers can block, pass, filter and tune the various currents of the radio. This device was likely used by Alfred Goldsmith for his experiments while he was the Research Director of Radio Corporation of America. Goldsmith aided in the development of the first commercial radio-phonograph.

- L. J. Marcy's "Sciopticon" Magic Lantern, 1869-1880 - Magic lanterns use a concave mirror and light source to project images on glass slides with painted or photographic scenes. Developed in the 17th century, magic lanterns predate slide projectors and motion pictures. In the hands of magicians, they became "lanterns of fright," projecting wondrous images and apparitions. Slide themes ranged widely: exotic travel, folklore, advertising, history, science, and art.

- Prodigy Interactive Personal Service Start-up Kit, 1991 - Before the Internet was accessible to the nontechnical public, consumers subscribed to networking services like Prodigy. Along with competitors like CompuServe and America Online, Prodigy promoted the Internet as a tool for information, shopping, and fun. This startup kit included a modem, software, and a free month of access to "a world of continually expanding and updated information and services."

- Transceiver, Section of the Original Ethernet, 1973-1974 - This is a section of the original Ethernet, developed by Bob Metcalfe and David Boggs at the Xerox Palo Alto Research Center (PARC) in 1973. PARC was a center of innovation; this pioneering internetworking architecture was developed to connect (PARC-developed) personal computers to (PARC-developed) laser printers. Ethernet has changed business and home computing and has reigned for thirty years as a global standard.

- Ediphone, 1917-1925 - Dictaphones and Ediphones were sound recording devices used for efficient oral dictation in business settings. When Edison invented the phonograph, one proposed use was "dictation without the aid of stenographers." Its tinfoil playback medium lacked quality, however. Alexander Graham Bell's Graphophone (later, Dictaphone) improved the phonograph by using wax cylinders for superior playback; cylinders were also used in the competing Ediphone.
