The listing, iMac/Laptop Ram has ended.
512MB (single SODIMM) 667MHz DDR2 SDRAM (PC2-5300)
I pulled this from my Apple iMac (Early 2006) the first week that I got it (I upgraded to 2GB); so it was used for a week and has been sitting in my desk since then.
This should fit a good number of laptops including many (but not the most recent) intel macbooks, you should google to verify.
Note: The sticker lists it as PC2-5300S-555-12-A2; the 555 refers to low-level timing, the part is 667MHz.
