Remember Heathkit? Then you are old. Anyway, Heathkit was a company that produced electronic devices (such as stereos). They were generally good, high quality devices that you could get much cheaper than market value, but they would arrive in the mail in pieces … totally unassembled, and sometimes with a free soldering iron.
You then got to put them together. After you were about three quarters through the project and realized that you had fucked it up beyond belief, you could then mail it back to Heathkit (on your dime) and they would finish the assembly for you and send it back. For a fee. So, the total cost was then higher than market value, but you got to have a lot of fun with your new soldering iron.
It is quite possible that Heathkit has been around since it was last on my radar screen (like, when I was twelve). In any event, thy have just come out with a new product, which is called the HE-RObot (Hero robot). It includes a Core 2 Duo Processor and it runs, unfortunately, Windows.
