Hello,
I have always wanted a Vic-20, and will get one soon.
In the meantime, I want to start to learn assembly language on the Vic20.
What assembler is out there, available for me to download and use in VICE?
I am going nuts trying to find one. I found a few for the C64, but none for the VIC20.
I've heard mentioned in here "French Silk", but all I found on the web is the interview with the creator.
Does anyone have a link to the download?
Any info would be helpful.
thanks
What Assember is there for Vic20 (using vice)?
Moderator: Moderators
The French Silk assembler, as I found out, is a little hard to come by.
I have tried three different native assemblers:
1. The French Silk "Develop 20" assembler suite (the one I think you are referring to)
2. LADS, from The Second Book of Machine Language by Richard Mansfield, and
3. ASSAM - Assembler and Monitor
Which one do I use now? ASSAM. You can download it from zimmers. It occupies 8k in Block 5 ($A000-$BFFF). It has both an assembler and a monitor, assembles to memory and disk, assembles from disk (big issues for a memry constrained computer like the Vic) etc etc.
I have never found any documentation on ASSAM, don't even know where it originally came from. However, it follows the syntax for PAL64 (the C64 assembler). All the pseudo ops are the same. So I use the PAL64 manual and I have never had any trouble.
Let me know if you have trouble getting any of these.

Thank you for the info!
I shall try assam, it sounds promising... just need to get it to load.
I tried loading it as a cartridge, but in vice it says invalid cartridge image.

also, for anyone else looking, i found the link to"develop-20", by French Silk... it was in this forum (just cant get it to run in vice)

That looks like the version of Develop 20 I found. I managed to get it to work using the instructions in the book "Inside the Vic" which is on:

Unfortunately I think it was the tape instead of disk version, so a bit annoying. Ultimately, after trying all three, I settled on Assam.

Woops - only half of the reply made it. That version of Assam runs at $2000 (pretty useless). Get the version that loads & runs at $A000.

Once loaded as a cart (or from disk), a SYS64802 (reset) will install the assembler. After that, SYS700 (as per the PAL64 manual) will run the assembler. SYS40969 will launch the monitor.
Here is a link to a copy of the PAL64 manual.

I got assam to load
Ok, i found some link to an application called prg starter...
I use linux, so I had to run some older version, that I needed to compile.

Re: I got assam to load
I'm afraid that sooner or later you run into the limitations of the size of the screen and the memory of the VIC-20. So you could already start to think of a cross assembler. If interested, I wrote my own (dis)assembler in Turbo Pascal, which can be compiled by Free Pascal http://freepascal.org/. Which is available for Linux as well.mikem wrote:I use linux

Hmm, I guess a cross compiler is the way to go. I like using vim as an editor, so thats a bonus.
I'm interested in this cross compiling, as it seems to be the way people are programming these new Vic20 games. So if I can get your (dis)assembler, and it would help ease the pain of code entry that would be great. If its failry easy (for a newbie) to use, let me know.
I did see the cc65 out there too.
thanks
