[Cialug] Free junk

The models I'm thinking of didn't have a conventional print head per 
se... they had a bar that was the width of the entire page (for the wide 
120 column paper), with 120 pins in it. The entire bar was mounted on 
cams, and oscillated around so fast you could barely see it. The pins 
would fire as the bar rotated past the desired position, kind of like a 
chain / band printer, but with pins. It was amazing to watch them print.
