4MB 72 Pin SIMM RAM Stick TMS44400DJ Texas Instruments Vintage 1990s Memory Module

Vintage 72-pin SIMM RAM stick marked 4MB with Texas Instruments TMS44400DJ chips. This module likely dates to the early to mid 1990s and was used in classic desktop systems. Clean contacts and no corrosion. One module included, shown in photos. These vintage RAM sticks are untested. I don’t have compatible hardware to verify functionality, but they appear to be in excellent physical condition—no bent pins, corrosion, or visible damage.
