This 1983 intro to computers book for young children has as much detail in a few colorful pages as a college hardware architecture class. https://archive.org/details/Usborne_Guide_to_Computer_Jargon_1983_Usborne_Publishing/mode/2up
@th Great find! Wonder about the age group. Some years back I was at the computer history museum in California. They have a wall illustrating the historic development of computer languages. Beside it was a young boy about 7 years old that had very strong opinions to his mom about even now obscure languages. Only in silicon valley I thought and grinned.
@th I see from the illustration that they predicted out-of-order execution by several years.
