||1994: The Pentium FDIV bug error was isolated to the Pentium Pro chip by Professor Thomas R. Nicely at Lynchburg College, Virginia, USA while working on Brun's constant (the sum of the reciprocals of the odd twin primes).  Nicely had noticed some inconsistencies in the calculations on June 13, 1994 shortly after adding a Pentium system to his group of computers, but was unable to eliminate other factors (such as programming errors, motherboard chipsets, etc.) until October 19, 1994. On October 24, 1994 he reported the issue to Intel.  The bug was rarely encountered by average users (Byte magazine estimated that 1 in 9 billion floating point divides with random parameters would produce inaccurate results)
