The Nec is driven by a VGA card (Tecmar I believe) while Cadvision is driven by an Nth Engine graphics card. The catch is that the Nth card is very expensive, about $4000 (not to be taken as gospel). The reason it is able to coexist with other video cards is because of its onboard memory, 2 megs of what is call "display list ram". Supplied with it are various drivers (ACAD rings a bell). All support software (drivers) are for the DOS environment, other operating systems, XENIX, QNX, etc, would need the development of their own drivers. Our application involves computer mapping and tracking of objects and utilizes both screens. Unfortunately I am not involved directly with the graphics end of the project so some of the particulars about the card are a bit fuzzy. If anyone is interested, I can look up and mail, or even post the specs. Please note that I am in no way associated with Nth graphics, Nec, Tecmar or even Cadvision, and these opinions are my own.
