4MB Kit (4x 1MB) Texas Instruments 30-Pin SIMM FPM Desktop Memory RAM (Model: TMS4C1024DJ)

A premium matching 4-piece lot of legacy 30-pin SIMM (Single In-line Memory Module) desktop RAM modules, providing a total capacity of 4MB (1MB per individual stick). This high-quality set is engineered on original green PCBs marked with the M1V-0 94V-0 production code and fully populated with premium Texas Instruments (TI) Fast Page Mode (FPM) logic chips (TMS4C1024DJ).Operating at a standard 70ns/80ns latency, these modules feature a classic high-profile 9-chip parity layout design. They represent a highly reliable choice for retro-computing purists and vintage hardware restorers looking to expand or repair the system memory of iconic systems from the late 1980s and early 1990s. They provide excellent period-correct performance for configurations running Intel 286, 386, or early 486 motherboards, early Apple Macintosh computers, and legacy MIDI hardware samplers.
