AMD’s reputation as an off-brand companyThere seems to be a conception that AMD, at this stage in the late 1980s and early 1990s, was a second-tier, off-brand chip maker. This has more to do with the effectiveness of Intel’s marketing than anything AMD was doing. AMD was not a stranger to the enterprise market. When you look at teardowns of 1970s and 1980s minicomputers, you frequently find AMD chips like the AMD2900 series ALUs inside them. The IT managers who shunned AMD CPUs in the 1990s most likely used AMD technology earlier in their careers on minicomputers without having any idea.
