MEMORY ADDRESS DECODING Address decoding is accomplished using a GAL16V8 programmable logic device. Address lines A<8:15>, AS (address strobe), R/W (read/write), and E (clock) are processed to provide the memory control signals as shown below by default. Custom configurations, differing from that shown below, are also possible. Contact the factory for assistance in redefining the memory map if required. Output enable to U5, U6, and U7 Write enable to U5 direct, and to U6 and U7 through jumper
