Old intros/demos use rastports for display of text and scrolltext with an own font, read via diskfont.library, that was a comon way in early amiga days.
Don't know of which early days you are speaking. When I was writing intros for the Amiga (almost 20 years ago, the real early days), people were using pictures as font sources. See example attachment.

what means "LVO" ?
"Library Vector Offset". These are labels so that you can use names for calling functions instead of remembering the numeric offsets. Also "jsr _LVOOpen(a6)" is much more readable than "jsr -30(a6)". The labels are predefined in amiga.lib.
