In general, Suns will use "ttya" as their console port any time they
are turned on with no keyboard plugged in. So, the answer might be as
easy as plugging a keyboard into your 690, unplugging the keyboard
from your 670, and plugging the VT100 into the 670. This is the
behavior when the boot prom thinks the input device is "keyboard" and
the output device is "screen".

In your case, there is a chance that your 690 has been configured
to always use the serial port as the console. So, what I'd do is
to first plug a keyboard into it (and attach framebuffer and display
if not already), and see if it comes up in the display. If it still
comes up on the serial port, do this at the "ok" (boot prom) prompt:

	ok setenv input-device keyboard
	ok setenv output-device screen
	ok reset

Things should churn for a little bit, and your 690 console should
now be working from your keyboard and screen. Now move the VT100
over to the 670, unplug the 670's keyboard and turn it on.

If you want the 670 to use the serial port for the console even if
the keyboard is plugged in, use these boot prom commands:

	ok setenv input-device ttya
	ok setenv output-device ttya

More detail should be available in various manuals, but this should
help get you started.
