I have been continuing to experiment with “automating” some version of the staggered leaf, and have reached a “final” punchcard version. Wanting to add a border top and bottom and getting the 2 ends to “match” without a center pivot point led to the resulting fabric below (swatch is not properly blocked).
The punchcard for the leaf pattern is over a 100 rows in length.
I actually had never purchase anything on ebay. The length of the card repeats I want to play with led to my looking for punchcard rolls. “Back in the day” the ones available were clear, and not numbered or marked in any way, a relative “pain” to use. Through an online search I found this item and purchased it. The order was filled very quickly. The roll is of sturdy stock, with Studio numbering so a bit of added markings are required for use on Brother KMs. I live in an area with no local suppliers for this sort of thing, buying directly from overseas was an option I had not considered before, and proved to be a positive experience for me.
Prior to google translate, google chrome, etc. barring having friends that spoke the language and knit, here were some resources for translations

The top illustration below creates what some demonstrators back in the day would refer to as a heart cable trim. The width of the strips of knit may vary, and the size of the holes need to be accommodated to suit the subsequent threading. The second illustration set results in a more traditional “pretend” cable. I-cord could be used for the second sample. Narrow strips of knitting will curl in however, and in many instances may be substituted for true i-cords. Because each pass of the carriage knits a row as opposed to slipping alternate rows, the knitting is twice as fast. In the instance below a series of holes are created for threading cording (or other chosen material)
The following illustrates threading option with a single length of the cording, which will need to be secured at each end with some stitching. Separate colors could be used on alternate sides for more color variation, and other threading sequences as well

Cables on multiple brand KMs including some reversible at knittsings. A technique that first appeared in Japanese knitting books that “cheats” in creating cables by knitting tuck stitches that are regularly rehung on the back of the work was embraced by Ricki Mundstock, who published copyrighted designs extensively for a while, and named the technique magic cables. Superba was another machine knitting brand that may be familiar. At the site there is a thorough discussion of hand transferred lace patterns on the machine with clear illustrations and suggestions that could be applicable on most brand KMs.
In terms of charting software for designing one’s own pattern charts some sites to explore: Aran paint, Stitchmastery, Sweater Project, Knit Visualizer, Intwined Pattern Studio, and 2 online chart generators: Chartgen, and Knitting Chart Maker by Jacquie, in addition to previously mentioned tutorials such as those by Marnie MacLean.

In creating large scale cables in the pasts tension changes, supplemental threads, and other ways to compensate for moving larger number of stitches on a metal bed (things start to get hairy when crosses become larger than 4X4) have been discussed. An interesting, clear, possible solution to produce textures or macro cables such as in this piece
may be found in her books and may be viewed in her youtube video. Handknit interpretations that also add lace to the mix may be found in Shirley Paden‘s portfolio photos of garments, she is the author of
Cables seem to be in vogue once again in myriad permutations. They pose some interesting issues when created in machine knitting. Interweave Knits Winter 2011 published an article on “Cables 101” that includes a way to color code and graph cable crossings. Some complex variants for those who like KM hand techniques may be found at Knit, not Knit , their courses here. “Back in the day” of regular, world wide machine knitting seminars several authors provided collections of machine knit cables including George Le Warre at Passap universities (copyrighted, George presently in England).
Simple crossings are a good place to begin and produce texture. If one is not interested in freeform but rather constant, recurring patterns it is possible to use punchcards to produce visual cues when stitch twists and crossings are to occur. This is not an option in Studio Machines, easy on Brother because of the fact that needles pre select, and Passap pushers may be used for a similar set of clues with a bit more fiddling.
When color coding information for referencing as one works, it is possible to be generous with symbols or edit down to bare elements. For example, one way to approach a schematic follows below, where knit stitches are illustrated as well as cable crossings. Red indicates stitches moved to the front, and the green indicates those traveling to back in each cable set. In hand knitting vertical or horizontal bars would represent knit and purl stitches. Since these are identical in this HK graph, they could all be eliminated
B the isolated repeat
The choice then remains whether or not to revert the crossings to match the HK pattern. One way to do that is simply to reverse positions for colors. The mantra becomes “red moves first, green moves second and over red”.
With all machines if the knit carriage is left set for normal knit, even if the patterning option is engaged (KCI or KCII if there are any needles out of work) needles will be selected, but the fabric produced is stocking stitch. The usual considerations are in order: the number viewed on the card outside the machine corresponds to the design row being read by the reader, but the punchcard holes in view are not necessarily the same as the design row selected. Because one is producing the cables on the purl side of the knit, if hand knitting charts are used the cables themselves will be mirrored. In many instances this may not matter, but if one is using the twists for representational crosses ie. in trees, owls, diamonds and other geometric shapes, it is a good idea to scan the repeat, mirror the image vertically, and then begin translating it into machine knit interpretations. Relatively easy with simple scanning and printing software (ie. the flip horizontal function in Preview, a bit harder by hand.
When I can I color code my cards: ie. with lace I draw a line across the card when I reach each knit row sequence with color pencil. This provides me with an easy to follow visual cue as to when the rows must occur, and also facilitates returning to previous selection sequence when mistakes in patterning occur.
Some basics: with a punchcard there is no row length limitation, but repeats are limited to 24 or a factor thereof. In this particular use wherever needles are selected, one has a visual reminder to move those needles in the desired direction.
I used the cards below to illustrate the idea in my intro to knitting classes. When needle selection occurs in the first, remove the selected stitches off the machine with a 3 prong tool in each desired location, then insert a second 3 prong tool back through front of those same stitches, in turn removing from the initial tool used. Rotate the twice transferred stitches 180 degrees consistently either clockwise or counter-clock wise throughout, and return them to their original position on the needle bed. The result is a consistently textured fabric with no counting stitches or rows between repeats.
a swatch using it
This card begins to address regular cable crossings, mine was punched in repeat the full 60 rows. A color may be assigned to help with opposing twists’ directions ie. to left (pink) or to right (green) when the corresponding color bar appears just above the card reader.
