[TriLUG] Items to give away

[Pete Soper]

The Diablo print wheel has the font characters on the side of the 
outside of the wheel, facing the same direction as the wheel axle. This 
Univac printer did not have a daisy wheel, it was unique. It had the 
font on the outside edge of the wheel. Every character faced outward 
such that a line from the center of the wheel coming out would point at 
the middle of the spot it was going to print on the paper when the 
hammer behind the paper struck.  I was using this thing at the same time 
Diablo developed their printer (1972).
Here's a description of a similar unit, 'cept it's obviously more recent 
as it offers paper tape instead of punched cards (that deserve a place 
in history as the ideal fireplace starter):
