I'm not sure what you're saying. The 8086 was introduced in 1978, while the 8088 was introduced in 1979. The 8088 is essentially the same as the 8086, except the external bus is 8 bits instead of 16 bits, which reduced system costs. The original IBM PC selected the 8088, not the 8086. The Intel chip numbers are all over the place. For instance, the 8048 series had parts ranging from the 8020 to the 8749; the "7" indicated EPROM.
