Students at CMU's Computer Club obviously don't see much reason for preservation if it stops them from creating demos like the one above, which recently won first place at PixelJam, a demo competition taking place at Ohio arts and technology conference Notacon. Since no compositional software exists for the system, esteemed chip musician C-Jeff composed and ported over the music from a ZX Spectrum, which has the same sound chip as the Vectrex. They then ran the resulting audio through a preamp to eliminate the harsh buzzing sound that gets mixed into the signal due to the machine's screen. The tripod camcorder recording doesn't quite fully capture the cathode rays' hypnotic glow, but since the console has no video outputs it's the closest you're going to get without owning one of these rare machines.

Captured using a camera aimed at the Vectrex CRT. Audio recorded through an add-on preamp board with line output to record high-quality audio without the Vectrex 'buzz'.
