It’s been modified.
Test the key, still not function, it is normal.
We will do the modification again

Modifying made simple
The numbers in sequence range from 1-F
When adding increments of 400 keep in min 4+4=8, but 8+4=C
[0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F]

Here is the number sequence without the testing and retries involved.1006 >1406 > 1806 > 1C06 > 2006 >2406 >2806 >2C06 > 3006 > 3406 > 3806. to clarify, the last 2 numbers are just to be copied as presented. the Lonsdor k518 machine automatically adjusts them each time it’s read, and the end result is unpredictable. just think of the numbers as [0000]- 10 – (XX), where the x’s are just to be copied and just follow the rest of the sequence follows the above pattern adding “0400” each time.
