Although the list below is a constant work in progress, I hope you will find it useful. Let me know if you see punch-card models that are missing.
Also, if you are new to machine knitting on flatbed machines and you just got a machine, consider the beginner-friendly projects I recommended to all my students and customers.
Unless specified, all machines below accept punchcards with 24-holes (to knit in 24-stitch repeat patterns).
