Notes:Pins designated should be in the closed position. A total of 64 base I/O addresses are available. The jumpers are a binary representation of the decimal memory addresses. Jumper JP1/F is the Least Significant Bit and JP1/A is the Most Significant Bit. The jumpers have the following decimal values: JP1/F=8, JP1/E=16, JP1/D=32, JP1/C=64, JP1/B=128, JP1/A=256. Configure the jumpers and add 512 and the values of the jumpers closing pins 2 & 3 to obtain the correct memory base I/O address. | ||||||
