1. Long after the advent and even the widespread use of digital computers, many
of us came into frequent contact (e.g., in school) with so-called "overhead
projectors", which projected light through transparencies onto a screen or wall.

It was not uncommon for the projector to be outfitted with a transparency roll,
on which the presentor wrote with a grease pencil or a marker during projection,
and which the presenter scrolled using a hand crank.

Scrolling was typically right-to-left; that is, the projected images moved
toward the left, with fresh, unmarked transparency moving in from the right.

The viewport thus moved to the right through the images/text, though no one
would have spoken, in that context, of a viewport.

2. Others of us have used film in movie projectors or film splicers.  Likewise
tape recorders and players, on down to cassette tapes of various sorts.  All
scrolls by another name, though no one would have spoken of them using that
