This chip is a 100% direct equivalent to the M086B1.

• Condition: Used (socket pulled), tested and fully functional.
• Protection: Shipped in high-quality anti-static foam and an ESD-safe bag to prevent physical or static damage during transit.

Important Note: Due to the vintage nature of this electronic component and the risks of improper user installation (static shock, incorrect orientation), this item is sold as-is with no returns. Please ensure you are comfortable with vintage IC installation or consult a tech before purchasing.
If you have any questions or need specific details, please feel free to ask. Thanks for looking!
