I have a Northgate that has 2 ADB ports and 1 PS2 port on the back of it. Does anyone know if there is a way to daisy chain an ADB keyboard off of one of these ports, then connect the other to your system with PS2? I tried it and it didn't work, but I thought maybe you could tweak it through dip switches or programming to allow this and save me from buying an iMate ADB to USB converter.
