 JSR HYPNOISE           ; Call HYPNOISE to make the sound of the hyperspace
                        ; drive being engaged

 LDA #4                 ; Set the step size for the hyperspace rings to 4, so
                        ; there are more sections in the rings and they are
                        ; quite round (compared to the step size of 8 used in
                        ; the much more polygonal launch rings)

 JSR HFS2               ; Call HFS2 to draw the hyperspace tunnel rings
