Asteroids Rediscovered

Well, I am very sure that all of you must have played the very popular game by Atari which was named as Asteroids. If you haven’t played one in an arcade you owe it to yourself to do it, because they look like nothing else. The phosphor artefacts are trippy and beautiful. The only problem with these was they used to get driven like a analog oscilloscope which deflects the electron gun to a certain spot on the screen at a very fast rate so that the output seems continuous.

They used a Xilinx Spartan-3E FPGA on a Nexys2 dev board which was programmed to be the vector generator, and a DAC/Amplifier board was designed to sling the beam around at 20 MHz and 12-bit resolution. First thing they did was get a cube to display on the scope. After tweaking around they managed to wrote a rasterizer and to display patron saint of Bed Stuy on the screen.
