Hand-Drawn Barcodes for the HP41

[cruff]

That was real dedication to draw those. Back when the barcode wand was released, I wrote a program for the 9825 at the lab where I worked to draw barcodes on the 9872 plotter. We used a modified drafting pen and balanced it with a small weight on a screw so that the 9872's pen mechanism could raise and lower it. I avoided damaging the nib from repeated landings on the paper by drawing them with a connected line along one edge. That setup worked really well and made nice looking barcode.
