This is a vintage ram upgrade for Macintosh Powerbook laptops, with a mark on the top indicating it adds up to 10 megabytes. Because I cannot properly test this card as I don’t have the hardware to test it with, I’m selling it AS IS/UNTESTED, and cannot guarantee its function. It is however in great cosmetic condition, with no signs of scuffing, corrosion or water damage.

Feel free to ask if you have any questions, and thanks for looking!
