Digi 50000478 DigiBoard Acceleport 8-Port DB25 Serial Card w/ PSU

The Digi DigiBoard Acceleport is a multi-port serial expansion card designed to add additional RS-232 serial communication ports to legacy computer systems. The Acceleport line was widely used in the 1990s and early 2000s for expanding serial connectivity in workstations, servers, and industrial control systems that required multiple simultaneous serial connections beyond the built-in COM ports.

Applications

The Acceleport was a production-standard solution for adding serial ports to legacy systems, particularly those requiring multiple RS-232 connections for printers, modems, data acquisition equipment, test instrumentation, and industrial control devices. It was commonly deployed in point-of-sale terminals, industrial workstations, laboratory data collection systems, and server environments running DOS, Windows, OS/2, and Unix-based operating systems. The card dates from the mid-to-late 1990s era of ISA bus computing. Today, these cards remain valuable for vintage computing projects, legacy system maintenance, and retrofitting older equipment with modern interfaces via serial-to-USB adapters.
