Description
Mitsubishi WEPR10 DC280179D 8-Bit ISA Parallel Interface Card DB25 Vintage PC
The Mitsubishi WEPR10 is an 8-bit ISA parallel interface card designed to add or restore a standard parallel port to IBM PC, XT, and compatible desktop computers. Part number DC280179D is silk-screened directly on the PCB. The card provides a DB25 female connector on its bracket for connecting parallel peripherals such as printers, external drives, or data-transfer cables. I/O address is user-selectable via an onboard 6-position DIP switch block (DTS-6), supporting standard addresses 0378H or 0278H.

Applications
8-bit ISA parallel interface cards like the Mitsubishi WEPR10 were standard expansion hardware for IBM PC and XT-class computers throughout the early-to-mid 1980s, a time when parallel ports were the dominant method for connecting printers, plotters, and external data storage devices to personal computers. The 8-bit ISA bus (originally called the PC bus) was introduced with the original IBM PC in 1981 and remained widely used through the XT generation before the 16-bit AT bus expanded the standard. Cards of this type are used today primarily for maintaining legacy industrial, scientific, or specialized PC-bus systems where a parallel port is required and the motherboard does not provide one onboard — common in CNC control systems, older test-and-measurement workstations, and vintage computing environments. The selectable I/O address via DIP switch made these cards flexible for multi-port configurations or conflict resolution in systems with existing parallel ports.
This Mitsubishi WEPR10 DC280179D 8-bit ISA parallel interface card has been inspected and is in good condition. The PCB is clean with no visible damage, broken traces, or missing components. The DB25 bracket shows light surface oxidation typical of age, and the ISA edge connector contacts appear intact. The DIP switch block is present and all positions are moveable.
