compucorp 320g scientist
|portable scientific calculator made by
the computer design company (CDC) in 1973. this is the base model of the
320 series which included the 322g and 324g.
it takes 4 D cell batteries (yes D cell), and has a rather nice orange
display (sunshine obscures this in the picture).
this unit was built with the mindset of a lab instrument, and probably
cost just as much. its very well built and can be dismantled for
servicing. the designers really cared about the precision of the machine.
it operates to 13 digits and displays 10+2 with scientific display ranging
over 10^ +/- 100.
|if scientific or engineering calculations are part of your
routine, then you've made a wise and logical choice in acquiring the
micro scientist. packed under the micro's powerful keyboard is an
instrument of great complexity, designed to take the drudgery out of
complicated mathematical calculations. it is much easier and faster to
use than your slide rule and more accurate than the tables you've been
indeed it is, and amazing that this machine is older than this
it has 10 memories which can be used with the basic ops to
perform sto+, sto-, sto*, st/ and (unusually) rcl+, rcl-, rcl* and rcl/.
even a^x can be a constant. note that a^x is the general x^y function
(non-integers allowed) a can even be negative if x is integral, which is
cool. brackets nest to two levels.
|like i said, its portable!
it comes in a special padded carry case and mains PSU which also
charges the 4 ni-cad batteries.
