content: Removing four screws from the bottom of the machine releases the cover. One circuit board is at the base, one holds the tubes that make up the display, and one lies under the keyboard. The calculator chip on the base has a Texas Instruments logo and reads: TMS0118NC (/) C7339. The "7339" is date code that refers to the 39th week of 1973, which is when the chip was manufactured.
label: Description
content: A February 13, 1973, article in the <I>New York Times</I> lists Muden as one of several companies that sold electronic calculators. On August 17, 1976, Ultima Electronics, Ltd., in Melville, N.Y., filed trademarks for MUDEN (first used in commerce in the United States in June of 1976) and ULTIMA (first used in commerce in the United States in October of 1975). These trademarks were registered in 1978. By 1989 Ultima Electronics was in Taiwan. As the Eletac 10 never gained wide sales, it seems likely that this example was sold about 1976.
