4MB 72 Pin SIMM RAM Stick Panasonic MN414400J Vintage Memory Module 1990s Collectible

Vintage 72-pin SIMM RAM stick labeled 4MB using Panasonic MN414400J chips. Marked with a “BAD:Y” label by a previous owner—unknown if that refers to performance or just vibes. One module included. Gold contacts look clean with no visible corrosion. 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. All information provided (capacity, speed, model numbers, etc.) has been sourced online and may not be 100% accurate, as documentation for vintage components can be limited or inconsistent. Please do your own due diligence to confirm compatibility and specs before purchasing. These are being sold as collectible or legacy parts, with no guarantees expressed or implied.
