I am somewhat new to this. Forgive if my description is not clear.
I have two code blocks. I know that each block, in part, codes for a serial number (which I know). Part of the code probably relates to a model number (which I know).
Each block is a 9x9 array. However, I believe the close two dots at bottom right are anchors and orient the code as seen in the attached images. Therefore, I believe the coding array to be 7x8 extending up and left from this location. The columns could be two 4 bit or one 8 bit?
It is possible that the serial comes from a (proprietary) lookup table and will not be directly gleaned from the code blocks.
Does anyone have ideas on extracting these codes?
edit to add: Image 1 is the upper left. Image 2 is the lower right.
edit to respond to comments: Hi @Lanny Strack , Yes, those are good papers and I have them both. That's right, I believe you sum up the papers well - the coding portion is the 7 column by 8 row grid. The two close dots at bottom right are to orient the code. @retzler has placed the coding into an array. If we look at Peter Buck's paper, (https://www.researchgate.net/publication/325976319_Reverse_Engineering_the_Machine_Identification_Code ) we can, perhaps obtain some clues on how to proceed with a possible decode. However, as I said in the OP, there may be a lookup table involved (which would dead end us).
