*** UNKNOWNS
*** Where are number of rows and columns in current pattern stored,
*** for ppreprogrammed patterns
*** What effect does the 'M' button have?
*** What effect (if any) does detection of a G carriage have?
*** TODO
Document changes to directory entries when programs added and deleted
*** NOTES
*** Memory can be cleared by entering 888 (from service manual)
*** This work was greatly helped by prior work performed by John R. Hogerhuis and posted on the kminternals yahoo group.

Beginning of file format documentation
--------------------------------------
*** Note about the following section -
*** This data is BCD, and the data for each motif
*** are not byte-aligned. In this document, each
*** index into the file is listed twice - MSN first
*** then LSN
format is:
0xnnnn: MSN
0xnnnn: LSN
*** Here are up to 99 entries for each custom program that may be saved
*** These have program numbers 901-999
***
*** Program memory can extend dowward into the directory entry
*** Space - This seems to be able to cause problems for the knitter.
*** For example, if you add a first user program (number 901) of
*** 140 stitches x 96 rows, it will fill memory from 0x06DF down
*** to 0020. The next time you try to save a program, the knitting
*** machine hangs up.

*** These previous seven bytes of pgm info data repeated up to 99 more times
***
------------------- [Snip]
0x02B7: last byte of maximum pgm info entry 99 - End of pgm entries
*** End of 99 custom program entries ***
***
*** Custom programs grow downward in this space
------------------- [Snip]
*** Programs grow downward from here
***
*** Program storage consists of the memo information for the program,
*** starting at the highest address and growing downward. Memo storage
*** is one nibble per row in the pattern, padded by one nibble for an
*** odd number of rows
*** Program rows of stitches are stored as a bitmap, stored from LSbit to MSbit,
*** LSnibble to MSnibble, and padded out to a complete nibble at the
*** end of each row. The entire program is padded out to the next
*** complete byte at the end.
