68k Software with calibration patterns?

[Brooklyn]

Hey, is there any 68k / System 7 compatible software that displays calibration patterns for CRTs? Trying to touch up the convergence on my M1296

I know for certain there is, but I just can't remember what. Might be TechTool Pro that has a screen pattern generator. I just can't remember.

There are likely others but Apple Personal Diagnostics can do that:

There's also Larry Pina's (of Dead Mac Scrolls fame) Test Pattern Generator and the follow-up color version.

Thanks guys! I also found setting my colors to B/W one of the desktop patterns ends up being white grid on black background!
