Having failed to deliver the real Keyboard Component, the Entertainment Computer System add-on was produced to settle looming lawsuits and stop fines being imposed by the FTC (see the Intellivision Lives site for the full story). I'm still saddened by that. I really, really wanted that computer.

It seems that there were also Intellivision, Inc. releases of the ECS software, but I don't know the complete list. The only three I know of (either that I own or have seen on various web sites or eBay) are Mind Strike, Mr. Basic Meets Bits 'N Bytes, and Super Series Big League Baseball, the repackaged version of World Series Major League Baseball. If you've seen any others, let me know!
