HP 1818-6838 8MB EDO SIMM Memory Module D3647B 16MB Kit

HP 1818-6838 8MB EDO SIMM Memory Module D3647B 16MB Kit

This is an 8MB EDO SDRAM DIMM module, half of HP's D3647B 16MB memory expansion kit. EDO (Extended Data Out) memory was a standard memory type for personal computers and workstations throughout the mid-to-late 1990s, bridging the gap between FPM (Fast Page Mode) and SDRAM. EDO modules like the 1818-6838 were commonly used in HP Kayak and Pavilion desktop systems, as well as various HP business-class computers and workstations of that era.

Applications

EDO SIMM modules were standard memory upgrades for personal computers and workstations during the 1990s. The HP 1818-6838 was designed for use in HP Kayak and Pavilion desktop systems, machines that were popular in small office, home office, and consumer segments. Two of these 8MB modules together provided the full 16MB capacity of the D3647B kit. While these systems are now considered vintage, EDO memory modules remain collectable and are sought by computer historians, retro computing enthusiasts, and those maintaining or restoring classic HP systems. This module is fully compatible with other EDO DIMM slots in compatible HP systems and can be paired with another identical module to achieve the original 16MB configuration.
