Bouncy Ball 2 this week, we have been experimenting with the GIME, building utilities and playing around with some concept art.
Bouncy Ball 2 Progress Report 1. First things first. We need to get the Coco 3 into it’s high resolution graphics mode, then display a little something. To start out small, I decided to create a program that sets the video mode, uses the MMU to map in the video memory, then clears the screen. That part was easy, although understanding the MMU was a little whacky.
I’m happy to announce that Bouncy Ball 2 development has started! Design is underway, and the sound system already sounds awesome. We have been able to make the Orchestra 90 sound mad. It’s using full stereo sound, mixing 4 channels, and uses hardly any CPU. We have a lot to learn about the Coco 3. Join us every week or two on the BB2 development blog to watch our progress. We are Lee, Simon, and Paul.
Radio Shack Catalog Number 26–3143. The Orchestra–90 CC is a stereo 8-bit audio player for the Color Computer. It works by mapping two addresses in the Coco’s address space to two 8-bit DACs. $FF7A is for left, and $FF7B is for the right. This is the first time I have been able to use this cart, never mind program it! So far, it’s pretty easy to program.
