Shahid,

There's similar, but not identical traces on the solder side, fat traces
originating at the IC and the pattern is somewhat repeated. The board was a
form, fit, function replacement for a hand laid board done circa 1975.

I'm being coerced to make my layout identical to the revised board, but I
don't want to manually route if I don't have to (we make too many changes
from review to review).
