There’s a special place reserved in my digital heart for the classic arcades like Tempest and Asteroids, and ironically it’s because of the flawless analog goodness of their vector-based displays. I still boot up a Tempest emulator for the Dreamcast from time to time, though while it remains fun to play, it just has no soul on a standard CRT.
The ZVG connects to your PC via parallel port, and Zector claims it is able to drive most old analog vector monitors that you are able to obtain. It’s even able to drive an oscilloscope in X/Y mode. VectorMAME provides the ZVG drivers for DosMAME, which would allow you to put together a MAME cabinet that will play all of the old vector games on a real X/Y monitor. The hardware will set you back a couple hundred bucks, but it appears that this might be the only way to play some of your old favorites in all their glory.
