It was 8 bits but now is 6 again 'cos 8 is very very very very very slow. With 6 only very very very slow.
Simple shift register. One bit set through 6
Only one logic output used but two LEDs connect. Q and Not Q.
"Not Q" only works with NO three-state gates.
On my Android everything goes very slow. I don't know if you have the same problem but I can't do more.
