    Older fashionista barbie in excellent shape. Seller indicated box damage but it was minor and did not negatively impact the doll at all. Good price, arrived quickly, packed well. This seller has a lot to choose from and is recommended.

    As described. Forgot to ask for shipping box. Came in a mailer but did not have top sealed with additional packing tape and delivered half unsealed. Appears to be intact and adorable. Was not for collectible so all is good.

    Still Works

    Here's the tips I have for programming the RCX 2.0 Windows XP 32 Bit Virtual Machine using Parallels or Virtualbox You can find the iso of the Robolabs online to install it Getting the Driver the IR tower is the most difficult task, however, i just looked it up on line in drivers tab "online", and it found it. despite it being windows xp, so actually pretty simple. Don't get Windows 8SE, the graphics that come with the VM don't meet the requirements for the Lego Robolabs software to program the RCX 2.0.
