It does appear to be the 4 x 1.15MB version. There's
an HP warranty label on the back that dates it to
1982.
Old (pre-about-1997) HP devices (not just computers, but test gear too)
have serial numbers of the form
yywwCnnnnn
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.
