z/VM and z/VSE allow 3215s as their consoles. z/OS does not. z/OS requires a 3270 full screen console.

I know what works and what does not. I never dug into what was different due to the settings. Most likely, it was something not in the specifications that z/OS happened to use, or had added for some reason, to the 3274 long ago.
