Vintage Compaq 72-pin SIMM RAM Module

This is a vintage computer memory module, specifically a 72-pin Single In-line Memory Module (SIMM). The item features a green fiberglass printed circuit board (PCB) populated with multiple black plastic integrated circuit (IC) chips. These chips are identified as Texas Instruments (TI) TM248NBX36B-70 models, which indicates a Fast Page Mode (FPM) DRAM type with a 70ns access speed. The module is manufactured in Singapore, as silkscreened directly onto the PCB. A prominent white adhesive manufacturer label is present, bearing the COMPAQ logo and the part number 129041-002, marking it as an original equipment manufacturer (OEM) part designed for Compaq deskpro or server systems from the mid-1990s. The gold-plated edge connectors are clean and show minimal insertion wear, suggesting careful handling. The overall condition is excellent for its age, with no visible signs of corrosion, missing components, or physical damage to the traces. This 36-bit parity module was common in high-end x86 computing architectures of the 486 and early Pentium era. The craftsmanship is typical of industrial-grade electronics from that period, featuring precise surface-mount soldering and durable board construction that has resisted delamination or discoloration over several decades.
