Yes, I am old enough to remember the years 1994/1995, when Intel has introduced the split between the "Pentium Pro" CPUs intended for "professionals" who should pay dearly for the right of having computers that function without errors, and the "Pentium" CPUs (2nd generation Pentium @ 90/100 MHz), intended for the naive laymen, whose computers are not important, so it does not matter if their computers make mistakes from time to time.

This market segmentation introduced by Intel has broken the tradition created by IBM, who had taken care from the beginning to provide the IBM PC with error-detecting memory.
