Hjalfi calculates finances with a Casio P2-D financial calculator

In which yr hmbl svt plays with a 1983 financial calculator with integrated chain printer, and which it will become obvious he's not really qualified to use. This is an electronic adding machine in pocket calculator form, intended for summing columns of figures and making simple monetary calculations with a full paper transcript. I got this because of the printer, but the actual calculator part is interestingly weird as well; it doesn't work anything like calculators I'm used to.
