The signals are around 30 for the main side and 6 for the "jump management" side. It may be useful therefore to call this "5-Level" (the conventional usage) to distinguish it from Murray's 5-unit code punched lenghtwise on the tape. The 13 punched holes in the postcard was the initial attempt by the Zodiac Killer to show us that the "crackproof" 340 cipher was a Dick Tracy style code. The smaller hole (I seem to recall that it is offset from the center so there are 3on one side and 5 on the other side of it so to know which side of the tape goes against the reader) was used for moving the tape thru the reader or the punch.

A smaller sixth hole was punched between the third and fourth bits for purely mechanical reasons: it allowed the paper to be pulled through the punch (and later the reader) very cheaply using a small toothed wheel. Both commands and data were represented by the presence or absence of holes in predefined positions. Below each of those numbers are 5 holes, representing 1 bit and labeled 16, 8, 4, 2, and 1.

Makes a very unique wedding band! The early designers were faced with the problem of adapting the Hollerith card to the 36-bit word used by the 704, especially how to bootstrap the machine with the punched-card loader program. Below each letter, they write the corresponding number using an encoding table (a=1, b=2, etc). cyphercon4. Input devices can convert the data or instruction into the machine-readable form and sent it to the processor for further processing. on a more practical line - send it as straight ascii, using the ham radio interfaces in Linux, through the sound card. The full name is actually ‘DMX 512’, because with it you can control up to 512 different channels. It read cards by row starting from row 9. The "Start point" of the decode tapes was an inked line across the tape, quite close to an inked number. Band measures 8mm tall and 1.2 mm thick on all sizes.
