Back in the late 1980's, apple released a version of Unix called A/UX. In order to get excitement going about it, they sold Macintosh computers with A/UX preloaded to developers. The combo was cheaper than the equivalent Mac. So I bought two of them. I also bought the biggest displays for them; they weighted like 50 lbs. Probably 400 x 512; I don't remember. Anyway, I hooked both up to their displays and both booted to this message:

When in Danger

Or in Doubt

Run in Circles

Scream and Shout!

Apple eventually admitted that A/UX didn't support those giant monitors. I installed Mac OS and it ran fine.
