Codename VEC9 - Early demos

The VEC9 is a vector generator system I've been working on with Todd Bailey and Adam Stankiewicz for an original arcade game using an electrohome g05 (asteroids) monitor.

I've been writing the vector generator in VHDL for a spartan3e on a nexys2 board. The x/y/z are controlled by (hastily put together) R2R DACs. It's an actual processor, fetching opcodes out of dual port RAM that can be modified via USB.

Early test of a raster to check draw speed of the monitor.



Wrote some custom software to use it for visuals at 8static. Hooked it up to a Tenma oscilloscope (great color trace and lighter than the tek!), pointed a VHS camera at it and ran the composite feed to a V4 - worked out really well! Mirroring effects look really neat and the camera sensor picks up the beam in a great way, used the Genesis to overlay some of my effects.
