My first ASM
-
I stumbled upon this book in my APress account today and it is so nicely written that in 10 minutes I wrote my first Assembly language program and ran it. Beginning x64 Assembly Programming: From Novice to AVX Professional: Van Hoey, Jo: 9781484250754: Amazon.com: Books[^] Over the years I've looked at Assembly and tried it out a little, but it's never been easier to try than now. I have Debian running in a VirtualBox so I quickly: 1. installed nasm (Netwide assembler). 2. Installed GCC tools 3. installed make 4. created a makefile as led by the book 5. typed in the sample program 6. let the makefile build and link the program. 7. ran it. That's very cool. This author is obviously really good because he gets right to the point and explains things clearly. I am impressed and I always like to read a good book that is so well-written.

To whom it may concern, here is a list with some alternatives: x86-x64-assemblers[^] FASM looks like fun too :-\

Haven't written any in over 40 years, since writing it on a PDP-10 while at university. But it definitely has a charm to it.

I got to use MASM with x86 assembly in undergrad. Wasn't a great experience. I've used it once since then, to cheat in a game that had anti-cheat protection. :-O

Wow, that is cool. I believe that might be the hardware that Gates and Allen began with. :thumbsup:
It was a great system, but maybe I remember it much as one remembers a first love. :-O

Yeah, that's how we all are with our first OSes. I even remember DOS 3.3 / Windows 3.1 fondly now. :laugh: Well, maybe not. But Win95, for sure. Pre-emptive multitasking was dreamy. Format a 3.5" disk while playing minesweeper was really cool. :laugh:

But does it cover 6502?

Indeed. My first brush with assembler was writing little games etc in Z80 code on a self-built NASCOM1 computer. My first major contract was porting MSDOS 1.25 to an IBM PC Clone. The disk drivers etc were all written in 8086 assembler. I can still see the thousands of pages of printed listing that I had to work on! (Filled with useless comments of the sort: "-- add 23 to AX")

Me too, also NASCOM1. No assembler, only machine language. I remember things like 3E 00 41 05 ...

Oh yes - you soon learned the various opcodes 8) I used to write it out as assembler on a coding sheet, write out the opcodes and then key them in! All these years later, despite the higher level languages and huge compute power, things haven't really changed as much as you might think. I just spent a whole day trawling through the code for a framework I'm using because its documentation tells you how to pass some data through to a sub-system, but absolutely nowhere, in text or examples, does it specify the format that data has to take! Doubly annoying because it isn't in the same format as you pass exactly the same data to the parent code 8)

Or Z80? 8080? 8008? :)

I started out with Z80 and 6809 machine code, there were no assemblers available to me back then. I wrote my first code like this around 40 years ago which was a ROM extension for Basic to control sound and speech hardware. Thinking back and comparing to the likes of modern assemblers or VS I have no idea how I managed it!

Check out Easy 6502 by skilldrick[^] I found this a great resource. And after watching the first episode of this series: https://www.youtube.com/watch?v=qJgsuQoy9bc[^] I realised I wanted to make my own emulator. Rather than follow the video series blindly I decided to do it in JavaScript and not follow the videos. This presented some challenges as JS doesn’t have Byte/Word types so that has to be managed manually. I’ve been trying to learn ASM for Gameboy, megadrive, z80, but didn’t get very far. Reverse engineering the code allowed me to properly understand each instruction and I am learning ASM as I go. Here is my WIP project: GitHub - gcoulby/MOS6502: CPD project to learning MOS6502 assembly language, which snowballed into reverse engineering the CPU[^]

When I wrote my first assembler program 25+years ago, I was so proud of being able to speak the computer's "native" language ! Like you could interact directly with its perception of things without the filters of the high level languages.

Exactly.

Not sure I agree with that. In 1979 I'd turn on my UK101 (similar to the Nascom) and it would prompt for BASIC or MONITOR. Choosing MONITOR gave you a 2-character input field where you could type in the hex value of the byte at address 00. Press ENTER and it moved to address 01. (You had to convert the 6502 assembly instructions into bytes in your head or on paper first, but there were only 56 instructions so it didn't take long to memorise at least the common ones.) :)
