Re: 6502 second processor poll

If you planned to make a game for a second-processor equipped machine, you might be interested in how many people are an in a position to appreciate it. For some purposes, the proportion matters, and for others, the absolute number. For other purposes, it's all just a bit of fun. Ultimately, all th...

Re: Palettemate / enhanced video ULA with 4096 colours

I'm very late responding to this thread, because Rob very kindly installed a VideoNuLA in my Master back in August. Due to real life, I've only just started playing with it properly and just need to say what a fabulous piece of kit it is and what a total gent Rob was for installing it for me (my sol...

Given the wide range of options now available, I'm wondering if the second processor can finally be consider standard equipment...

How to you plan "large" programs?

I'm looking for some guidance in writing "large" BASIC programs. I've broken the design down into a number of modules (screen drawing, input handling, processing specific events etc.) and I want to work on each module independently. But what's the best way to actually approach writing this...

I've got to ask what the going rate is for the new ULA board as I don't think I've seen a price for it (assuming there are still any available). They are £52.50 including UK P&P. I only have one left but I may order some more PCBs and make some more if there's enough demand. I'm in Newport so y...

The £ sign in variable names?

I'm reading through the AMX SuperArt manual and disk and there are a set of routines that are designed to make WIMP interfaces easy. The provided code prefixes the variable names with a "£" and I've not come across this before: 30010 DEFPROCinit 30020 DIM £M$(5),£I%(5),£T%(5),£X%(5),£H%(5)...

Re: *mzap and *define

It's probably not what you're thinking of, but the AMX Super Art ROM has a *DEFINE command which takes a filename parameter and is used to load up to 32 user icons and redefines characters 128 to 255.

Wanted: AMX SuperArt Manual

Hi

I'm looking for the manual for AMX SuperArt (NOT the AMX Art/Mouse guide that's online).

Would be happy with either a physical copy (for a reasonable price) or a scan.

Thanks!

Very enlightening answers. Thanks. In addition to the two ROMs mentioned here, can anyone think of others that extended BASIC?

Given that there are different ROMs that extend BASIC, did they all use the same method to add new commands (and if so, what's the method?). Is there specific functionality within BASIC and/or MOS for extending the language?

Re: Anyone developing Tube enhanced software?

The idea is generally to split the game, logic runs on the copro, display (sprite drawing) runs on the base machine (IO). Elite works nicely as nearly everything runs on the copro, while the base machine does input, sound and draws lines where it is told. As I understand it, OSWRCH is the correct w...

Re: Anyone developing Tube enhanced software?

The problem I see with games and the tube copro is that many games are host CPU bound for the graphics. So extra processing and memory which can't be used for graphics/sound doesn't help a lot. It would be great for a game like Simcity but for sprite arcade games a copro doesn't really help. Would ...
