VIC Assembly Cartridge Wanted.

[garry68]

Hello all,

I'm new to VIC 20 programming (well actually I'm really old to it, but I haven't done anything for around 30 years) and I used to have the Assembly programming cartridge - I gave it away around 20 years ago.

And was just wondering how much it would be to get one again now?

I was toying with the idea of making an machine code game for the VIC (hopefully for the unexpanded VIC) and would be grateful for any tips on where to get started (I do have a working VIC 20) and how to run programs on a VIC when developing on a PC.

I know this may all be basic info, but I'd rather get it from those who know rather than wade through a lot of garbled information on the internet.

Unless you are intent on developing on real hardware PC cross development is far easier

Personally, I use a combination of Notepad++ (with Exec and Explorer plug-ins), CA65 Cross Asembler & VICE emulator for testing. There are many other assemblers and tools too, such as my Vic20 screen and Character designer and CBM Prg Studio.

I intend to develop on the PC and port it across to the VIC, like I do for my Vectrex stuff (which I mostly use Notepad++ for).

If it's easy enough to get hold of the Assembly cartridge I would like this for tracing what is actually happening when something is run on the real hardware. Something I can't do with the Vectrex.

The Denial forum has two sections, 'Programming' and 'Emulation and Cross Development', which specifically deal with this kind of subjects.

That's much easier done with the built-in monitor of VICE.

Besides, the really interesting cases of cycle-exact routines couldn't be tested this way on real hardware, as those rely on the same resources (VIA timers) that are used by the single step routines of the monitor program in those cartridges.

HESMON or VICMON should go at around $5 to $10 on ebay. With a RAM expansion in BLK5, you could softload the cartridge images of those.

(hopefully for the unexpanded VIC)

Why just unexpanded? Those concerned running real hardware do own RAM expansions. Count on it.

Well, to see what I can manage to get in there, and because this is/was the standard machine...

But if everybody really does have an expansion RAM now, then I suppose I'd be a well making it for 16K.

As I said, I haven't really done anything with a VIC for a long time!
