If you intend (or would at least like) for other people to play/try out/use what you make, consider going with a Commodore 64 instead of a 128; for people with physical hardware, the 64 is far more popular and will have a wider base of users.

Of course the 64 is a bit more limited than the 128, but handling that is part of the fun of retrocomputing. “It’s not the lines that make playing Tetris interesting - it’s the walls.”

My family have explicitly stopped ordering from Dominoes because of how insane their pricing has gotten. We have lots of significantly cheaper pizza options in my area that that are as good or are better.
