Using the PROM/RAM/PLA Wizard 129
 Each string of hexadecimal characters (0–9, a–f, A–F) specifies one
word in the array. Words are entered starting with address 0, then
address 1, and so on.
 Any non-hexadecimal character (including blanks, non-hex letters,
punctuation and line breaks) separates one word from the next.
 Each hex character represents 4 bits, with the rightmost character
representing the least significant bits in the word (i.e., bits 3, 2, 1, and
0).
 If insufficient hex characters are given for the length of the word, the
rightmost character in the group represents the least significant bits and
unspecified higher order bits are filled with zeros.
 If all the words in the device are not specified, unspecified words are
filled with Don't Know (X).
 Line breaks can be inserted wherever desired except in the middle of a
word
 Items not containing any hex characters will be completely ignored and
just taken as separators. Don't consider this to be a method of inserting
comments unless you're sure you can spell everything without A to F!
 There is no comment mechanism.
 No error messages are given no matter what you put in the text!
