ZG400 1MB 72 Pin SIMM RAM Stick Rare Vintage Memory Module OEM Custom Build Early 1990s

Uncommon vintage 72-pin SIMM RAM stick featuring ZG400 and 11345 chips—possibly an OEM or proprietary configuration. Likely 1MB capacity based on layout and known chip patterns. A rare early 1990s piece for collectors or vintage PC restorers. One stick only. 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.

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.
