I've been thinking about this for a little while now, and it seems to me that in my old Elementary school, there were candy iMacs that could go all the way down to Black & White. I know this, because I remember playing a Muppet-themed educational game in school which repeatedly asked to be taken down to 16 colors, and the iMac went down every time I clicked OK. I also remember seeing a Black & White option in the control strip.

Perhaps this was a school-only version of the iMac, or possibly an upgrade card that allowed this?

I'd like to know if anybody here has seen or heard about these computers, and if they actually exist. I'd sure want one.
