My world view was based on news from computing magazines and messages embedded in demos (i.e. bizarrely limited compared to today) but at that time I was pretty sure I was the first who “opened” the middle of the C64’s side border to create an edge-to-edge horizontally scrolling text: https://csdb.dk/release/?id=742. My friend and co-crew member of the 1001 Crew helped set up a museum exhibition display featuring side border sprites last year: https://twitter.com/JoostHonig/status/1448624117289193478. We’re still in touch and like to reminisce about the good old 8-bit times. I’ll study this article at some later time to see if I can still match their approach with mine. I really should look at my code and annotate it some day.
