Welcome to this new blog dedicated to the learning of the Motorola 68000 Assembly language.



Overview



In this blog i will try to show you some simple ASM coding under the AmigaOS 3.x environment and mainly using the Amiga Devpac 3.18 assembly editor.

This blog will **NOT** explain you all the instructions of the M68K CPU. No need for this. Always prefers the officials documentations. On my side, I prefer to show you how to code routines in practice - rather than explains you the theory. Some others books and websites will do this much better than this blog. My point is a more practical approach where we will see things as long as we need them.




Environment


The environment setup for the next lessons is quite basic. For what we will need to do, a basic AmigaOS 3.1 (or even 2.x) without any third-party apps is enough.

My choice of using Devpac instead of any other ASM programming editor is only because i find the Devpac editor very OS friendly, easy to use and it have a handy Debugger (Monam) that i know how to use. But PhxAss or ASM Pro are also very good alternatives.

As a easy start, you could use a real Amiga, WinUAE, or FS-UAE in addition to ClassicWB for example.
