The Odd Story of Factory-Downgraded 486s (2020)
I've got a similar story.<p>In 1998 a had a summer job, as a programmer, in a little shop that built computers. At the time there was a short of Pentium II 300Mhz chips. One day the logistics guy mentioned they had gotten a batch of Pentium II 300Mhz marked with an operating voltage of 2.0V, instead of the usual 2.8V. Hmm.<p>Intel had taken a bunch of their most expensive CPUs, PII-450Mhz, using the brand new 250nm process and rebranded them as the cheapest CPUs which were at the time built with a 350nm process. You could just take this, stick in a motherboard an change the base frequency and you'd have the best CPU Intel could make.<p>We never sold any of those CPU to customers. We all bought ourselves new CPUs that day.
