Description
The DEC 54-21277-HA is a memory module designed for compatibility with systems that utilize the Single In-line Memory Module (SIMM) form factor. This particular module offers a capacity of 32 megabytes, which was a common specification for memory upgrades in personal computers and workstations during the late 1990s and early 2000s. Its designation as AS255 suggests it might be a part number used within a specific DEC product line or a compatible third-party offering. The SIMM interface is characterized by its edge connector that plugs directly into a motherboard slot, providing a compact and relatively simple method of memory installation compared to earlier technologies. This module is suitable for users looking to maintain or restore older DEC systems or other compatible hardware that requires this specific type and capacity of memory. It represents a piece of computing history, catering to the needs of vintage computing enthusiasts or specific industrial applications that rely on legacy hardware.
