Did any other brands used Atari inc brand shells with labels for their releases?

If this is a copy and not legit I have a 14 day return on ebay. So anyone who can help me it would be appreciated.

Looks like they're used in conjunction with cassette tapes. Fairly rare it seems. I could be wrong, but I thought I remembered reading years ago that some of these smaller companies did used cannibalized cart shells for their own software.

Yep it's an Atari board with a plugin play adapter for Rom chips. Glad this was found cheap cause I wasn't sure what it was. Thanks for the info
