the other vector board

I took at the other board that I have from the Space Fortress
and it looks more like the original circuit (except they didn't
use a good cap in the vector 'integrator', they just used a
disc ceramic (YUK!). It uses two National DAC1221's and a LF13331.
Instead of the discrete brightness inverter, they use a 7404
on the brightness inputs. TL082's on the outputs..
