Old (pre-about-1997) HP devices (not just computers, but test gear too) 
have serial numbers of the form


Where : yy = number of years since 1960 (note, this might be a single 
digit on really old stuff)

ww = week of mnaufactuer (sometimes adjusted for the average time it 
takes to get the unit from HP to the custormer)

C = country of production (A = USA, B = Brazil, Q = UK, G = West Germany, 
S = Singapore, probably others too)

nnnnn = serial number in that week, etc.
