What was known as the first computer

Mauchly and J. Presper Eckert at the University of Pennsylvania. ENIAC was also the first machine to use more than 2, vacuum tubes, using nearly 18, vacuum tubes. Storage of all those vacuum tubes and the machinery required to keep the cool took up over square meters square feet of floor space. The ABC completed one operation about every 15 seconds. This meant the program was fixed and designed to do a single task.

This also meant that, to solve these problems, an operator had to write down the intermediate answer and then feed that back into the ABC. Atanasoff left Iowa State before he perfected a storage method that would have eliminated the need for the operator to reenter the intermediate results. Atanasoff never filed a patent for his invention. This allowed them to claim they were the inventors of the digital computer. Want more?

Since all that remained was one of the drum memory units, it was hard to prove otherwise. They were able to demonstrate that the ABC did function. Hello, curious kids! Just the other day I actually found an obituary from a Canadian paper from that—extremely unusually for Lovelace obituaries—focused entirely on her Analytical Engine paper. So I was pretty delighted.
