You're still not being specific enough. Since this technology is over 30yrs old I am assuming it's for a class of some sort... am I right?

What your asking for is the instruction code otherwise called the machine language code for a intel 8086. They haven't used those chips in a long time except now they use them in diagnostic tools and in cars to monitor the system.

Machine code - Wikipedia, the free encyclopedia

These chips became popular in the IBM personal computers when they first came out and the one following it was the 8088.

The rival chip at the time was the 6502. Comonly used in Atari 2600 video game consoles.

The first apples were based on that chip. (6502)

There are numerous sites on the Internet explaining Intel instruction sets and assembly language programming. Google is your friend.

Examples:
Wikipedia: x86 Instruction Listings
The Intel 8086 / 8088/ 80186 / 80286 / 80386 / 80486 Instruction Set
Complete 8086 instruction set

Intel may still have their developer's manuals which included an instruction set reference on their web site, however I wasn't able to locate documentation for processors earlier than the 80386 but I didn't look very hard. The 8086 Family User's Manual may be of interest.
