Learn 8086 (x86) Assembly Programming - Lesson1 : For absolute beginners!

This is the first in a series of tutorials which will teach you how to write your own games and programs in 8086 assembly from absolute basics - using only free software!

This tutorial assumes you have no previous experience of programming at all, and teaches assembly using DosBox and the 186 based WonderSwan

All the episodes have a matching text lesson on my website, and you can get the development tools and scripts, and source code as well...

My Books cover most ASM languages and are available on Amazon stores worldwide! Now in Hardback and Large A4 size!
My 1st book covers ASM programming on Z80, 6502, 68000, 8086 and ARM
My 2nd book book covers ARM Thumb, 65816, 6809, PDP-11 and Risc-V CPUs

The Large print versions can be a little hard to find... the links are here:

Learned more in the first 20 minutes of this video than the first 4 weeks in my college assembly course. Thank you so much for making these!

[noname]

Wow, it's really cool to see you tackle the big one.

You are legit a savior for going slow and steady because I'm struggling in class right now and i only understood now why i needed to store certain items in certain registers. Thank you! Subbed and liked!!

Gawd, I remember when I was in middle school, trying my hand at x86 ASM and making funky colors and text. Funniest thing was, I only used Debug. Nothing else.

Ah yes. When assembly programming for Intel chips was still simple. Really interesting step up in processor technology from the 6502 for instance. I still have the books for assembly programming on the 8086.

I can say without a doubt that you have the *best* assembly tutorials on the entire internet.
I love assembly language (especially x86 and ARM), and program for DOS and the GBA.
However, a lot of this information is hard to come by online these days, and when you do find some resources (especially for DOS)
it tends to be cryptic.

These tutorials have proved invaluable in my game and software development escapades.
keep up the good work.

I've given this video PROPER SUBTITLES! Please turn them on if it helps!

I really like your videos. Can't wait to follow this series.

Retro Computing is a really great field of study and so thank you for making videos about this field and attracting people to it. It is good to learn how to program Retro Computers!

[MaslowsInferno]

Fantastic, thanks so much for this. In an 8086 course this semester and this enhanced my reading greatly.

[spacewolfjr]

Awesome video, thanks! Looking forward to more.

Love your web site, didn't know you had an youtube channel.

[jsimoesdias]

This is great! Been waiting for this one for a long time. Just want to say that your cheatsheet goes to a 404, if you are not aware.

21:10: I wonder if modern assemblers (or any assemblers) also let you put single-quoted UTF-8 characters beyond US-ASCII into registers, so long as the register size can accommodate the number of UTF-8 code units (i.e. bytes) that the character's code point requires?
For example: The 16-bit AX could accommodate U+0000 thru U+07FF, since these characters (the first 1/32th of the BMP) are only 2 bytes long in UTF-8. The 32-bit EAX could accommodate U+0000 thru U+10FFFF. The 64-bit RAX could accommodate e.g. flag characters like 🇷🇺, which comprises two 4-byte code points.

Have you made a tutorial on how to setup notepad++ with DosBox and the compiler?

[jercommodore]

Any chance of a 8085 series?
Please, please!

In a 32 bit system, would ax be the lower 16 bits of the 32 bit eax register? similar to how al is the lower 8 bits of ax?

[oa]

Can u make a tutorial on multiplication of 32 bit numbers on 8086 pls.
