The first one looks like you are triggering on noise or runt pulses. What
does it look like if you set the trigger level much higher, say half of the
full voltage?
One thing to try... Switch to single shot mode. Turn the room lights way
down. Your eye will remember the picture for long enough.
The simple solution is to get a digital scope.
