You simply need to set the switches to signal what number memory card you have on the computer, e.i. the first 128K will have pin 1 on, the second 128K will have switch 2 on, card 3 - switches 1,2, the number is coded in binary obviously. With these set, the jr should recognize all memory. If not, you may need an additional power side-card. The jr itself can power only one side card reliably. To power more than one or two, you will definately need an add-on power card. This should be of some help. **************************************************************************** * Thank You, texbell!letni!rwsys!trsvax!slimer * * Bill "I love it when you talk COBOL!" - ComputerWorld * * George W.
