Applications
The IBM PS/2 line was introduced in 1987 and represented IBM's move toward the proprietary Micro Channel Architecture bus, designed to replace the aging ISA bus with a higher-performance, bus-mastering alternative. The Model 6875 and 6885 were mid-to-late-1990s IBM workstation and desktop systems that used MCA alongside conventional ISA slots. Today these boards are sought after by collectors and technicians maintaining legacy IBM PS/2 systems in industrial, government, and institutional settings where older IBM hardware remains in service. The 40H4760 is a direct replacement/spare board for anyone repairing or restoring a 6875 or 6885 chassis.
This IBM 40H4760 PS/2 System Board (for 6875/6885) has been visually inspected and appears to be in good used condition. It was pulled from a working environment where it had previously been in service. The board shows normal wear consistent with its age, including light surface oxidation typical of vintage IBM hardware — no cracks, broken traces, or heavy physical damage are visible. The processor socket is unoccupied; no CPU, memory, or cables are included. Please review all photos and contact us with any questions before purchasing.
