Summarize this article for a 10 year old
The Altair 8800 is a microcomputer designed in 1974 by MITS and based on the Intel 8080 CPU.[2] Interest grew quickly after it was featured on the cover of the January 1975 issue of Popular Electronics[3] and was sold by mail order through advertisements there, in Radio-Electronics, and in other hobbyist magazines.[4][5] According to Harry Garland, the Altair 8800 was the product that catalyzed the microcomputer revolution of the 1970s.[6] It was the first commercially successful personal computer.[7] The computer bus designed for the Altair was to become a de facto standard in the form of the S-100 bus, and the first programming language for the machine was Microsoft's founding product, Altair BASIC.[8][9]

The Altair 8800 had no built-in screen or video output, so it would have to be connected to a serial terminal (such as a VT100-compatible terminal) to have any output. To connect it to a terminal a serial interface card had to be installed. Alternatively to using a terminal Altair could be programmed using its front-panel switches.
