Hi all, I'm trying to get two of these to work in a single PC XT so I can max out the memory. I have figure out the 'left' set of dip switches sets the memory starting address, but need to determine the functions on the right set of switches so I can modify the printer port I/O address, serial port address, and hopefully the size of memory that it thinks is on the board. Any help would be appreciated. Thanks. -- Pat
