"Click below", exactly 'where below' does one click? I clicked all over your post with no response.

You have to have Flash installed.

 

If installed, you should see a scaled up image of TI-99/4A title screen. Click inside this area to direct user input to the application, and then press any key to begin.

 

If not installed, the implementation on AtariAge should give you the option of going to Adobe's Flash Player Download page.

Wow! Love it! I think the multi-colour stuff could work on real iron, yes?

Yes, and probably at lower frames per second (fps), but then I'm assuming you're running the Flash thing on a not too old CPU.

 

 

Wow! Check out standard graphic 1. AWESOME. Can you code this up on real iron???

Yep, the standard graphics 1 would be the least processor hungry (768 locations whereas multicolor has 4 times as many). I was using a "palette" of 21 "colors" (and that's then 21 different characters), and since then, I actually think a longer and better "palette" could "easily" be made. Like more subtle gradients.

 

Each location or pixel has 4 of these to deal with, so I'll have to look into ways of making it fast on the 9900. And the sinus is using a lookup table approach already.

 

a = x1 + time - 32 + ctr1;
b = y1 - 128 + ctr2;
v = sinT[int(((a * a + b * b) / 20000) % pi2 / step)];
