Board numbers of the form Xyyyy are _not_ DEC part numbers

	'''DEC part numbers''' are generally of the form 'ww-xxxxx-yy zzzz' (sometimes the first hyphen is omitted). [[Digital Equipment Corporation\|DEC]] had a system for their part numbers, such that looking at a part number will generally tell you (based on the leading two-digit field, the 'class code') what ''kind'' of part it is: [[integrated circuit\|chip]], cable, etc. The next field is a 'basic identifier', then comes a 'variation identifier'; the final, optional, field is the 'revision identifier'. .		'''DEC part numbers''' are generally of the form 'ww-xxxxx-yy zzzz' (sometimes the first hyphen is omitted). [[Digital Equipment Corporation\|DEC]] had a system for their part numbers, such that looking at a part number will generally tell you (based on the leading two-digit field, the 'class code') what ''kind'' of part it is: [[integrated circuit\|chip]], cable, etc. The next field is a 'basic identifier', then comes a 'variation identifier'; the final, optional, field is the 'revision identifier'.

			It should be noted that DEC had several other [[namespace]]s for things produced by the company (such as [[DEC engineering drawing numbers]]; and the identification numbers of [[FLIP CHIP]]s and later component [[printed circuit board\|PCBs]], of the form 'Xyyyy', where 'X' is a capital letter, and 'yyyy' are digits), but these numbers are ''not'' 'DEC part numbers', as defined by the applicable DEC specifications (below).
