The AT correlator "External bus interface" is designed to interface to an 80x86 mother board's 8/16 bit ISA bus. The external bus provides addressing for 32K by 16-bit words of memory and six specific purpose 16-bit registers. The external bus consists of a non-multiplexed, 50 pin header, containing...
