And they weren't all that fun either, computers like ENIAC were actually just giant calculators that help people solve really complicated math problems.
Woz spent a lot of time at home reading his father's electronics journals, and he became enthralled by stories about new computers, such as the powerful ENIAC.
After working on ENIAC, Eckert and his colleague John Mauchly, set out to build a bigger and better computer called EDVAC, incorporating Delay Line Memory.
For example, the ENIAC, consisted of more than 17,000 vacuum tubes, 70,000 resistors, 10,000 capacitors, and 7,000 diodes, all of which required 5 million hand-soldered connections.
In the 1970s, the patent for the ENIAC technology entered the public domain, and it was able to be modified, becoming the blueprint for modern computers.
But there was a problem… In the era of one-off computers, like the Harvard Mark 1 or ENIAC, programmers only had to write code for that one single machine.
Although the ENIAC was developed to aid in WWII, it wasn't completed until 1946, when the war ended, and it was first used in calculations for the construction of a hydrogen bomb.
