The ISA-GPIB IEEE-488 Interface Module is an ISA bus adapter card that enables 16-bit computers to control and communicate with GPIB-compatible instruments and devices. Built on the CB7210.2 GPIB chip, it functions as a complete Talker, Listener, and System Controller, supporting IEEE 488.1 and IEEE 488.2 standards. The module delivers data transfer rates exceeding 1 MB/s using a high-speed state machine bus manager and 1024-word FIFO buffer, employing REP-INSW block transfer methodology without DMA assistance.
