my best guess.
ooh, almost, not a FGPA though. You probably have at least one of these in your house.wolram said:field programmable gates arrays.

Yes, I was looking for telephone specifically. You and Wolram can share the honor.Ivan Seeking said:I thought this was answered. It's a telephone.

Alxander Bain's proto "fax" machine?Ivan Seeking said:The parts list includes a transmitter and receiver, a stylus for each, and two large pendulums.
A fax machine from the year 1865
The idea of putting the achievements of telegraphy to good use in order to transmit photographs as well as printed texts and drawings dates back to the 1850's. The Pantelegraph conceived by the abbot, Giovanni Caselli, was a system of sending and receiving images over long distances by means of electrochemistry.
The stylus of the transmitter scanning an original document by moving across its parallel lines sent messages by telegraph to a receiver. The stylus of the receiver moving across a chemically-treated sheet of paper reproduced the document according to the signals received. Transmitter and receiver were syncronized by two large pendulums swinging in sync with each other. On 16th February, 1865 the Pantelegraph was introduced into service for the Paris and Lyons and the Paris and Le Havre on to the Marseille Railways. It was phased out in 1870. The machine on display in the Museum is a working model that was built for the 1932 Chicago Exhibition.
Wolram, this is a great thread. I love learning stuff this way.wolram said:who's next, if you find this stimulating, give me a what was, is ,it.
YES! You even got the maker correct!Nereid said:'transistor radio' - Regent?

Yep.Ivan Seeking said:...The RAT?
This is the correct food product. However, I must deduct .2 of a point for phrasing your answer in the form of a question. You have been watching Jeopardy too much.Lorider said:What is the potato chip?
Crepes would have been a better guess, if you were going to follow this train of logic. In any event, I was curious to see if you or Nereid were going to answer with "crisps" which is, I think, what potato chips are called in England: very thinly sliced potatos, deep fried in oil, heavily salted. Chef George Crum thought the customer who complained about the thickness and sogginess of his deep fried potatos would balk at his maliciously extreme fullfillment of his wishes. Instead, the customer loved them. It became a popular item on the menu. Other restaurants adopted the recipe. Potato chips became the rage, and still are.wolram said:pancakes ?
The purpose of the world's largest computer in 1951, known as the UNIVAC I, was to process and store large amounts of data for the US Census Bureau. It was also used for other tasks such as weather prediction and scientific calculations.
The UNIVAC I was approximately 8 feet tall, 7 feet wide, and 14 feet long. It weighed around 13,000 pounds and required its own dedicated room for operation.
The UNIVAC I was developed by J. Presper Eckert and John Mauchly, who were also the inventors of the ENIAC, the first general-purpose electronic digital computer.
The UNIVAC I had a processing speed of 1,905 instructions per second and could store up to 1,000 words of data. In comparison, modern computers can process millions of instructions per second and have storage capacities in the terabytes.
The original UNIVAC I is currently on display at the Smithsonian National Museum of American History in Washington D.C. However, there were multiple UNIVAC I computers built and some can still be found in museums or private collections around the world.
