Its next level of 8085 which was 8 bit processor. So 808x , where x may be next series of 8085 processor.

HI

The nomenclature follows:

80= Designed during 80s (released 1978)
6= 16Bit

I guess second "8" was so, because at the beginning of project they want to show it follows 8085. Another advantage was maybe to show this generation is source code compatible to 8085 and 8080. Therefore they should have kept it.

Was Intel 8008 designed in year 1900?

Knowing, that the first Intel processors have been 4004 (1971) and 8008 (1972), the next 8080 (1974) primarly designates a more powerful 8-bit device. I agree, that the 6 in 8086 seems related to a 16-Bit bus (in contrast to it's companion 8088).

"80"08

Its in 80's ....

In 8085 => "80" in eighties (1976?? hope so)
"8" Its 8 Bits processor
"5" It works on + 5 volt power supply ( instead of +/- 5 V; Dont evr compare these with 8086 ; in the sense that 8086 also works on 5V ; but as the others said "6" may denotes the 16 bit processor !! hope so ..)

Thanks guys
