< p > The calculator measures 74.2 mm x 135 mm x 22.2 mm . It weighs 86 g without the battery installed , which is a 9 v PP3 - type battery . Rather than the usual press - stud type holder , the housing has two metal slide clips . There is also what I assume to be a sponge at one end which is supposed to aid in holding the battery in , however it appears to have gone completely hard and I will most likely replace it in the future . There 's small adaptor hole at the top, of which the input isn' t specified ( though it 's generally agreed that it' s 4.5 v centre - positive ) .</ p >
< p > The case is black & amp ; silvery colored with a thin brushed metallic front panel . The eight - digit bubble display has an absolutely < i > terrible </ i > viewing angle , which means you either have to be holding it under your coat or against your face to read it !</ p >

The keypad is particularly strange in the way that it has 3 cancel buttons , [ CE ], [ C ] and [ CA ], while the [ CS ] button is a Clear Sign button , < i > not </ i > another cancel ! The keys themselves are particularly stiff , and you really have to push them to get them to register . Many 880 s suffered something referred to as the " pseudo fixed decimal bug " where , if you typed in 1 + 1.00 = , it would display 2.00 instead of the expected 2
