The Kaypro PC series comes with 768Kb (as do probably a number of machines out there) but the top 128Kb is used as a RAM drive by software that comes with the machine. In order to use more than the 640Kb, you need to use a driver of some sort; I believe that's ow it's done with the new extended memory, as well. Grant Prellwitz !ihnp4!gargoyle!sphinx!pre1
