> [In the 1980s] Microprocessors started to replace integrated circuits.

Author implies (in the quote above which occurs after the discussion of the invention of personal computers) that the early personal computers from the 1970s did not use microprocessors. This of course is false: All the early "personal computers" used microprocessors. For example the IMSAI used an 8080, the Apple II used a 6502, and the TRS-80 used a Z80. Microprocessors -- which were never intended to be the basis for entire general-purpose computers -- were repurposed for exactly that application by visionaries like Woz. Microprocessors made personal computers possible.

It would be more correct to state that in the 1980s microprocessors began to replace integrated circuits in mini and larger computers.

A subtle related point is that it would be even better to point out that by "integrated circuit" above the author really means discrete small-scale integrated circuit. All microprocessors are integrated circuits, but not all integrated circuits are microprocessors. Microprocessors are large-scale integrated (LSI) circuits or nowadays very large-scale integrated (VLSI) circuits.

There is a lot that is wrong in this article. Broad overviews are useful to people new to a topic - this would only mislead and confuse people.
