Product Description
The HP 20-136-70T, also known by its 1ST Tech part number 100032-70, is a legacy memory module belonging to the SIMM (Single In-line Memory Module) category. This specific module features a 72-pin connector, which was a standard interface for memory in personal computers and workstations from the early to mid-1990s. SIMMs were a significant advancement over earlier memory technologies, offering a more compact and easier-to-install form factor. This type of memory module was commonly used in systems that supported EDO (Extended Data Out) or FPM (Fast Page Mode) DRAM. The exact capacity and speed of the 20-136-70T module would need to be confirmed, as 72-pin SIMMs came in various capacities, such as 4MB, 8MB, 16MB, and 32MB, and operated at different speeds (e.g., 60ns, 70ns). These modules were essential for providing the system with the working memory required to run the operating system and applications of that era. Given its SIMM form factor and 72-pin connector, the HP 20-136-70T is intended for installation in older computer motherboards that specifically require this type of memory. It is not compatible with modern systems that use DIMM or SO-DIMM modules. This component is primarily of interest for maintaining or upgrading vintage computer systems.
