Description
A matching 4-piece vintage lot of legacy 30-pin SIMM (Single In-line Memory Module) desktop RAM modules, delivering a total capacity of 4MB (1MB per individual stick). This set is built on clean green PCBs featuring original, premium Samsung semiconductor logic chips (KM41C1000CJ-7).
Operating at 70 nanoseconds (70ns), these are Fast Page Mode (FPM) non-ECC memory modules featuring a classic 3-chip layout design. They are highly sought after by retro-computing hobbyists and collectors to restore or upgrade the system memory of iconic late-1980s and early-1990s hardware. They provide the perfect period-correct configuration for vintage rigs powered by Intel 286, 386, or early 486 processors, classic Apple Macintosh computers, and legacy MIDI hardware samplers.
