I'm certain it's a "tape-and-donuts" PCB layout. The first CAD-developed PCB's I saw in the 1980's had telltale 45-degree bends everywhere, and everything else was perfectly orthogonal.
Notice there are no traces going between 0.1"-spaced pads, due to the primitive manufacturing capabilities at that time. Remember when they used to gold-plate everything ? Some were so thickly plated they appeared to be solid gold. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
