By 1987 math coprocessors had become Intel's most profitable product line bringing in competition from vendors like Cyrix whose first product was a math coprocessor faster than the new Intel 80387, but whose speed was stalled by the 80386 that acted as a governor. This is when Andy Grove decided it was time for Intel to recapture its channel to market opening up a division to compete with its math coprocessor customers that by this time included 47th street camera. The new Intel division, PCEO (the PC Enhancement Operation) came out with a product called "Genuine Intel Math Coprocessors." After playing around in the accelerator board business PCEO would settle down in the 80386 motherboard business originally selling a motherboard designed by one of its engineers as a home project that eventually ended up with a new division that today sells 40% of the motherboards used in high end PCs that find their way into products including Supercomputers, medical products, etc.
