Coding in assembly on A500

04 July 2017, 23:50

Hey,

I've recently cleaned up my old Amiga 500 and would like to give ASM a shot. I've bought a null cable serial cable that should allow me to transfer .adf files and write them to a floppy. I am planning to write devpac 3 to a floppy and use that.

Will i need any additional hardware to get started or will this be sufficient? I attempted to install ASMONE 1.25 on an emulator and it was asking for a Hard Disk to install it onto. Will i need this for devpac 3?

Any help on this would be greatly appreciated as i'm a newbie to all of this.

Thanks.

No matter which assembler you end up using, you'll probably very quickly want to have an Amiga with a HDD in it as running from floppies is just too slow and tedious. I think Asm-One requires a hard drive. I haven't tried Devpac 3 but I know that Devpac 1 was designed to run directly from floppy (you'd want at least an external floppy drive for your code though).

Asm-One do not requires hard disk. Jut run Asm-One from floppy. It requires req or reqtools library only as far as I remember.

I'm using ASM-One 1.20 KS1.3 and KS2.0 on a floppy with my WinUAE A500 config. It requires:
- reqtool.library, asl.library in LIBS:
- (optional) REGSDATA and ASM-One.pref in S:

Long term, you will save a lot of time if you use a (virtual) hardisk. Especially if you decide to use Devpac.
Just in case, this is how you can do it: http://www.lemonamiga.com/help/tutorial_1/1.php

Seems a bit odd to me to use a floppy image for assembling in WinUAE since a HDD is free and just a few clicks away.

On a real A500 without HDD there is also the option of using something like an Action Replay cartridge to write your assembly if you want to really get back to basics.

Yes, you can certainly run Devpac from disk on a A500, but there are a couple of things to watch out for. The latest version of Devpac (3.18) requires AmigaOS 2.x+ so if your A500 is 1.2/1.3 then you need an earlier version (e.g. 3.02), which may be hard to find. Also, I don't believe the standard Devpac disk is bootable so you may have to boot into e.g. Workbench first and then swap disks. Or you can try to create your own bootable disk with Devpac on.

If you plan on coding anything system legal then trying to use all of the includes from floppy would definitely be prohibitive.

alkis · 05 July 2017, 19:56

Size of system includes for assembly seem to be 1.4mb in size.

Code:

find ~/gcc6/m68k-amigaos/ndk/include/ -type f -name '*.i' -exec du -ch {} + | grep total$
1,4M	total

If you must have big includes, it's hard to stay on floppy. But sth like the Asm-One V1.01 adf has the lib symbols for the usual libs and devices, and you can use that with a source disk in df1. I did this for the longest time, together with the Extern directive instead of Incbin to keep loaded files in memory between reassemblies.

I honestly recommend using a modern editor for your code, and just compile on the Amiga, if you can.
Things like code highlighting and the much increased screen space will be a godsend for you when you have large chunks of code.

Last weekend I tried to go through some code on Devpac 3 and I was really fucking annoyed, missed notepad++ so much. Never doing it again.

I don't do full fledged crossdev because I am a moron, but this works for me. I just have to swap an SD card around when I want to compile.

Tigerskunk · 28 July 2017, 15:39

Or use a modern Editor, and cross compile (with VASM, for example).

Saves you tons of time.

demolition · 28 July 2017, 15:48

Or if you really want to use some 68k native compiler, you can make a script with WinUAE with JIT enabled and it will be very quick as well.

I used to have an A500 with 2MB extra memory, and simply booted from a RAD disk with lots of Power Packer compressed programs including AsmOne. Worked very nicely.

Vasm is more of a replacement for PhxAss than for AsmOne. Different tools for different purposes.
