i agree that the B&W vector monitors display at a higher resolution than the Color XY"s this is all disclosed on the Zekctor web site., but why on earth why would you take a game like Tempest, or Space Duel and play it on a black and white monitor??, you might save maybe perhaps $100.00 to $150.00 on the overall project cost by going with a black and white monitor but in the end your not totally going to be satisified with the graphics on some of the color vector games.
To be quite hones the only true way to make a mame vector is to have one with two monitors, a black and white and a color or two entirely different cabinets, its really hit and miss with a mame vector, then youhave to worry about Veritcal Vs. Horizontal Orientation not to mention all the different control panel configurations, like Star Wars, etc.
to be realistic, for persons doing this project you should sit down and really come up with what you want to achieve with such a project come up with the games you want to absolutely play, and then come up with a game plan to come up with a control panel layout that will work for all the games on your list without having to swap around so much stuff.
the zecktor card is great, and it will allow you to play all the vector games, BUT not without pulling your hair out trying to figure out how to make the controls all work to pull it off., and if you dont do a good job witht the controls, then you have lost the battle....since it will not be fun to play or wont be like the real arcade game.
some of the games to me that would require a complete totally different control panel would be the Empire Strikes Back/Star Wars and then Lunar Lander. (whens the last time you seen a lunar lander control panel up for sale to rob parts from for a mame project/??)
it has its challanges but without making a completely huge ungodly looking control panel even if you were to play all atari vector games only there is NO WAY you could make a single control panel to play all the individual games, its definately going to be a chore to come up control panel.
i guess we all need to brain storm this (for those of you who are interestedin doing this project)
