Data Age Sssnake cartridge shape?

[fiddlepaddle]

A long, long time ago, I bought several Data Age carts when they were being blown out at Sears or Pennys in the 80's for a few dollars, and they all have an "angled" end (where the title is). This is also what I seem to remember seeing when I look through boxes of carts, though I've never really been focused on Data Age carts, since I already have them, and they're not usually that fun anyway.

 

However, I was just looking at pictures of Sssnake carts on ebay, and most of them seem to have an end that looks like a normal Atari or Activision style cart with regular 90 degree angle, although I can't be sure because of the typical camera angle.

 

So, I was wondering, did Data Age release carts both ways? If so, are the "angle" style less or more rare? Why did the style change? I can't imagine it was due to overwhelming demand...

They just had the one cartridge shell as far as I know.
