Traced the console port back to the 1488 that it’s connected to, and also determined that the Altos *is* wired as DCE which makes more sense to connect to terminals. The 1488 is connected to a Z80 DART. Got out the logic probe and the input to the 1488 just stays high.

Guess I need to start actually looking at the schematics. :-)
