I am stuck on what to use for buttons.  I am thinking elevator buttons.   Large oak case.  Just crank it for 10 seconds and then do  your calculation.   I am also conflicted as to how many buttons.  Square and square root for sure.  Undecided about log, trig functions and whether or not to have scientific notation.  I think I will.  How many digits to display?  Probably 5.  Engineering mode only.  3 dot 2 display.  Also considering multiple lines to show 4 levels of the stack but I doubt I will actually do that.    The question is: will I ever finish this thing? -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com
