This was seen usually just before the Stargate opens from Earth's end (though many times it was skipped for time)
The dialing computer was slightly different in the 1994 movie (It said SEQUENCE COMPLETE, instead of LOCKED)
This screen will respond to touch, and clicking the box of hexagons will unlock the speed (otherwise it will slide slowly)
