Looking for a free calculator with paper tape function and the ability to display fixed # of decimal points.
ESBCalc http://www.esbconsult.com/esbcalc/esbcalc.htm is close but insists on using 2 lines for each operation and doesn't do hex/octal/binary.
Moffsoft Freecalc has a better paper tape but doesn't do fixed decimal places nor hex/octal/binary.
