it possible for the 80287s that came with the AT to be overclocked to 12 MHz. 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. Companies like Hauppauge and Microway that were impacted by their new competitor that made their living accelerating floating point applications being run on PCs followed suit by venturing into the Intel i860 vector coprocessor business: Hauppauge came out with an Intel 80486 motherboard that included an Intel i860 vector processor while Microway came out with add-in cards that had between one or more i860s. These products along with transputer-based add-in cards would eventually lead into what became known as HPC (high performance computing). HPC was actually initiated in 1986 by an English company, Inmos, that designed a CPU competitive with an Intel 80386/387 that also included four twisted pair high-speed interconnects that could communicate with other transputers and be linked to a PC motherboard making it possible to create distributed memory processing computers that could employ 32 processors with the same throughput as 32 Intel 386/387s operating in a single PC. The add-in card parallel processing business morphed from the transputer to the Intel i860 around 1989 when Inmos was purchased by STMicroelectronics that cut R&D funding eventually forcing companies that had entered the parallel processing business to shift to the Intel i860. The i860 was a vector processor with graphics extensions that could initially provide 50 megaflops of throughput in an era when an 80486 with an Intel 80487 peaked at half
