[nfbcs] truth tables

[Mike Jolls]

Commenting on another responder, Excel is in fact a good way to layout truth tables.  However, here's a question.
What happens if you want to do some tabular work but you're not near a PC with Excel, or maybe your electronic solution has died?
OK, this might not happen very often, but in the event it does, and if you're not sighted where you can simply lay it out on paper like in the old days before we had software such as Lotus 1,2,3  (I'm dating myself there) or Microsoft Excel, what do you do if you're blind or your vision is such that you can't deal with pencil and paper?
Is the only choice Braille at that point?
 
I suppose if the answer is Braille, then you better have a 40 column slate and 11.5 inch wide paper.
And, hope that the data columns you need aren't so many that they won't fit in 40 columns.
 
I ran into this problem when I had severe cataracts and was considering doing it with a slate and stylus.
I have to say it was difficult remembering exactly how I was lining up columns and getting the placement right.
That's why I asked what you do if your electronic solution goes away.
Is there an acceptable Braille method to use when you don't have the electronic method available and you can't use Jaws / Magic / Excel or some similar solution?
