"I took some pics of the carts. The games are named:

B.Spiele [Interton #3]
Speed-Hight-Pilot [Interton #28]
37-Monster [Interton #37]
Kreuzer-U-Boote [Interton #7]
Jagt [Interton #12]
Kegeln [Interton #25]
Space [I don't remember, but I'll check that out this weekend.]

I got the games from an ebay-auction in 2005 (June). The games came
together with a Grundig console and some photocopied instructions. The
seller was from Nuernberg which is close (about 15 km) to Fuerth where the
big Grundig factory is/was. (I don't know the english word, but he was one
of those guys who clear flats, attics, etc. after the people died.) I
asked him about more informations on the carts (two or three times), but
he never answered. I took pics of cart #37 and emailed them to some
friends (back in 2005), but got no reaction at all.
  The carts are clearly selfmade. I think you can see that on the pics.
Three of the have the eproms directly on the board, four have sockets for
them.
  Do I want to dump them? Yes of cause, but I'm not able to do it by
myself and I'm not sure if I want to send them arround the world. I'm of
course open to suggestions.
  If you want you can put the pics on your homepage." - Jens Brinkmann.
