I was unable to find the files mentioned above, but this website hosts these original families. It also hosts a lot of the original houses such as the Maxis Mansion, my personal favorite.
I will include info here on how to install,
For families put the file you downloaded into C:\Program Files\Maxis\Userdata\Imports and then when you open the game click the import button.
For houses put the file in C:\Program Files\Maxis\The Sims\UserData\Houses. When you open the game it should show up in the neighborhood.
Depending on your computer it might be Program files(x86) and make sure userdata is whatever neighborhood you want so userdata2 would be neighborhood 2 and etc.
