A comment on Game Programming Patterns: Double Buffer (2014). Parent comment
While the Apple ][ had no graphics hardware to speak of, it did have two graphics buffers that you could switch between.
So you would draw into the non-displayed buffer and switch to that.
If you had installed the vertical-blank mod, you could even do that without tearing. (I think the //e came with that).
