Vintage 1985 IBM Personal Computer AT Guide to Operations manual, Part Number 6280066, still factory sealed in its original shrink wrap and slipcase.

This is an original IBM manual from the PC AT era and remains unopened in its original packaging. The factory shrink wrap is completely intact, with no visible rips, tears, holes, or evidence of prior opening.

IDENTIFICATION:

• IBM Personal Computer AT

• Guide to Operations

• First Edition, September 1985

• IBM Part Number: 6280066

• Original IBM slipcase

• Original factory shrink wrap

• Factory sealed / unopened

CONDITION:

The factory seal remains fully intact. Because the manual is still sealed, the interior pages and contents have not been removed or individually inspected.

There is some visible age-related discoloration beneath the original shrink wrap. The spine of the manual has small areas of brownish spotting/discoloration, and there is a light brown horizontal age line/discoloration visible on the back. These marks appear to be associated with long-term age and storage. They are visible through the original packaging and are shown in the photos.

There is no visible fuzzy or active growth on the exterior of the shrink wrap. Because the package remains sealed, the condition of areas underneath the original packaging cannot be further inspected without opening it.

The original slipcase is also included. Please review all photos carefully, particularly the close-up images showing the factory seal and age-related discoloration.

ITEM SOURCE / PROVENANCE:

This item comes from the remaining inventory of ABC Resellers, a Texas-based computer sales and repair business established by my late father. The business specialized in vintage computer systems, legacy hardware, components, and professional repair services. This inventory remained professionally stored as original business stock and is now being carefully liquidated and individually listed.

The inventory from ABC Resellers was accumulated through many years of my father's work in vintage computer sales, repair, restoration, and technical support. It represents a unique collection of vintage technology spanning generations of personal computing and includes systems, components, peripherals, software, networking equipment, and other legacy computer-related items.

My father spent decades working with and supporting computer technology, helping customers maintain older systems and sourcing hard-to-find legacy parts after many of these technologies were no longer readily available.

The specific acquisition history of this individual item is not known, so no particular acquisition source is being represented as fact.

Thank you for supporting the careful liquidation of the historic ABC Resellers inventory and the preservation of vintage computing history.

Please review all photos carefully, as they show the exact sealed item, original packaging, factory seal, and visible condition.
