One of the features added on the 68010+ Motorola CPUs is a special register called VBR – Vector Base Register, which allows the OS or user program to move the CPU’s vector table away from 68000‘s fixed address $00000 to some other address. On the Amiga, this was usually used to move the vector table to fastRAM, enabling somewhat faster interrupt processing. One of the utilities that allowed this was VBRMove. I usually have VBRMove…
So, we have rendered frames of our BoingBall, as described in Part 1. What you want to do next is check if the animation is seamless – that is, if it loops without glitches. Best way is to convert the frames into a .gif or .avi animation (in my experience GIF works better) with your favorite photo / video editor. You will also need to reduce the number of colors of your frames, I used just…
I’ve received some questions about how I made the new minimig logo with the rotating checkered ball, so I thought I’d write something about it for my first post. The BoingBall is quite famous in the Amiga land, as it was featured in one of the first demos made for the Amiga computer to demonstrate its capabilities at the Consumer Electronics Show in January 1984. It was later used as an official logo of the Amiga. Its roots…
It all goes back to … well, not that far back – 2013, to be precise, that was the year the .guru top level domains became available. Why guru you might ask? Well, the ‘guru’ part comes from the infamous Amiga error screen (sort of like a BSOD in Windows), which I always thought was a very funny way of letting the computer user know something has gone terribly wrong (especially if you know the origins of…
