3.6  Contemporary processors

Contemporary 16 bit processors to 8086/8088 were Zilog Z8000 CPU, Fairchild 9445 CPU, Texas Instruments TI9900 CPU and Mil-Std 1750A CPU. Last is the reason DoD (Department of Defence) contractors were not interested in 8086/8088. Mil-Std 1750A CPU was specified in all contracts of the 1979 - 1984 period.
Texas Instruments TI9900 CPU was probably the best of the lot, but Texas Instruments considered it a closed architecture, so no-one used it.
