UPDATE!!! Long overdue. Some very exciting things are happening. I've complete the XY deflection, High voltage section and crt driver for a plug and play kit that will work for most 5"-9" crt's and ordered the parts for a small run. James Sweet has also finished his vector daughter board. A board that plugs onto a cheap Altera Cyclone FPGA board and so far lets you run Asteroids and Asteroids Deluxe for true hardware goodness. I've added a couple pictures of the prototype deflection and James FPGA board running on a vectrex crt. The screenshot is terrible, but trust me it looks amazing in person.
