First microprocessor was (a) 8085(b) 8088(c) 8086(d) 80487?

Answer 1

80487 was the mathematical Co-processor for the 80486

8088 (8 Bit) was before the 8086. 8086 was the first 16 Bit processor.

8085 was never used for Personal Computers with DOS or similar Operating Systems.

Answer 2

Among that list, it would be the 8086. But the 8086 was not the first processor, as someone else stated, the first commercially available processor was the 4004.

Well, I learned something new, the 8085 was a processor after all.

Answer 3

Here's the answer:

The first developed CPU from those choices is 8085 by Intel.

but if you asking what was the first microprocessor developed by intel the answer would be 4004.

here's a list sorted by date:
4004 - 8008 - 8085 - 8086 - 8088 - 80486 - P1 - P2 - P3 - P4 .

hope this helps.

Answer 4

i dont know some of the microprocessors that u mention
but the first microprocessor for personal computers was 8008 microprocessor was not introduced until November 1972, the resulting flurry of activity was quite impressive. Only six months later, in May 1973, the first computer based on a microprocessor was designed and built in France. Unfortunately the 8008-based Micral, as this device was known, did not prove tremendously successful in America. However, in June of that year, the term "microcomputer" first appeared in print in reference to the Micral.

Answer 5

I always thought it was the 4044. From your list the earliest would be a) the 8085. I'm also pretty sure that the 80487 is a math co-processor for the 80486 (but I've been wrong before).

Answer 6

8085

Answer 7

(c) is commonly known as XT - I can't judge if (a) possibly was a development step without (large) sales.

Answer 8

(c) 8086

Answer 9

i think it was 4004...check out this website http://www.maxmon.com/1971ad.htm
