    I was curious if these things were still readily available, new. The Walmart site shows one at my local neighborhood market for $7. That’s crazy. I think I may grab one next time I drive that way.

    Later versions of Ghost require a 386 or better too. According to this version 4 requires a 286, so if running on a 8088, you'd need verion 3.x or earlier. I know I've tried version 8 on a 286 and...

    It’s probably for one of those Magnavox 80 monitors

    Maybe for a C128 so you get both rgbi and composite video?
