Travel straight back to the birth of the personal computer in 1981 with this historic piece of computing royalty: an authentic, original IBM Monochrome Display and Printer Adapter (MDA) 8-Bit ISA Video Card (Part No: 1501483 XM)!

Shipped as the premier text display solution with the legendary original IBM PC (Model 5150) and IBM PC XT (Model 5160), this full-length expansion board powered the iconic crisp green phosphor screens of the IBM 5151 monitor. Labeled directly on the PCB as "BLACK & WHITE/PARALLEL", this dual-purpose card combines IBM's classic MDA video controller built around the Motorola MC6845P CRT controller with an integrated Centronics-compatible parallel printer port.

Whether you are restoring a museum-grade IBM 5150 / 5160 XT build, typing away in early MS-DOS 1.0–3.3, or setting up a period-accurate dual-monitor MDA text / CGA graphics rig, this genuine IBM board is pure early-1980s computing nostalgia.

• Manufacturer: IBM (International Business Machines)

• Part Number: 1501483 XM

• Card Type: Monochrome Display and Parallel Printer Adapter (MDA)

• Silkscreen Designation: "BLACK & WHITE/PARALLEL"

• Bus Interface: 8-Bit Legacy ISA (Industry Standard Architecture)

• Primary CRT Controller: Motorola MC6845P (U35)

• Text Mode Capability: High-resolution 80×25 monochrome text mode (9×14 character matrix)

• Rear Bracket Ports:

  • 1 x 9-Pin D-Sub (DE-9 Female) Monochrome Display Output (for IBM 5151 or compatible TTL monochrome monitors)

  • 1 x 25-Pin D-Sub (DB-25 Female) Parallel / Centronics Printer Port

• Functional Condition: Vintage Asset / Untested. Card was pulled from an authentic vintage system. The 8-bit ISA gold edge connector traces are clean, straight, and intact. All DIP IC chips, socketed controller silicon, and ceramic capacitors are physically undisturbed. Sold as a vintage collector / restoration asset due to the specialized 5151 monitor requirements.

• Cosmetic Condition: Excellent vintage condition. The dark green solder-masked PCB is extremely clean with clear white factory silkscreen markings. No signs of battery corrosion, burnt traces, or lifted pads. The full-length metal mounting bracket and port hardware are straight and solid. Please review the high-resolution photos for an exact look at physical condition.

• Genuine IBM 1501483 XM 8-Bit ISA Monochrome Display & Printer Adapter Card (Bare Board)

• Note: IBM 5150/5160 computer, IBM 5151 monitor, video cables, or printer cables are NOT included unless explicitly pictured.

Early 1980s full-length ISA cards contain delicate socketed chips, sensitive TTL logic, and exposed PCB traces that demand top-tier shock and static protection. This card will be sealed inside an anti-static ESD bag, cushioned generously with multiple layers of heavy-duty bubble padding, and shipped inside a rigid, oversized box to guarantee a safe arrival to your vintage computing workshop.
