BOCA EUD-5U9-BRI4065 IO Board

The BOCA EUD-5U9-BRI4065 IO Board is a legacy ISA bus I/O expansion card that provides dedicated parallel and serial interfaces for compatible systems. It uses a GoldStar GM82C455 dual UART chipset and offers a DB-25 female connector for a parallel interface and a DB-9 male connector for a serial interface. Configuration is performed via onboard DIP switches and jumper headers. The board bears markings EUD-5U9 and BRI4065 and carries FCC ID E4UD5U9. Listed as a used module, it may show minor cosmetic wear yet is described as fully operational. This combination of ISA bus connectivity, DB-25 parallel and DB-9 serial ports, and a dual UART chipset makes the EUD-5U9-BRI4065 suitable for connecting legacy peripherals and enabling basic I/O expansion on ISA-based systems.
