I have two things to share. First, I am involved in an ongoing project to preserve the tapes used by the Mego 2-XL toy robot (1978-1981) and the Tiger 2-XL toy robot (1992-1995). You can view our progress and find links to the archived audio here. I'm still working through digitizing my personal collection.
Second, I am working with the developer behind a browser-based 2-XL simulator to enable people to play with a virtual 2-XL robot. It was originally done in Flash some time ago, but he is now looking into remaking it in HTML5. While he is doing that, I am passing along my digitized tapes to increase the available library for his simulator.
Both sites are also great for other stuff.
