A book or >text file that someone has compiled will do fine. Thanks. There is a book out by Microsoft Press called "The Programmers PC Sourcebook" which has all kinds of interesting information in it, including chips on different standard cards and thier port locations. It includes most of what you have asked about here I believe. If you can find it in a bookstore and thumb throuhg it you may find it interesting. It goes up through 1988 as the publish date, so has info on the VGA display cards. Wim. -- wbonner@yoda.eecs.wsu.edu 27313853@wsuvm1.csc.wsu.edu 27313853@Wsuvm1.BITNET 72561.3135@CompuServe.com
