At some point, IBM redrew the traces for the IBM CGA card - there were originally lots of 90 degree angles, the new version is all smoother 45 degree angles.

This change happened after the redesign of the CGA's composite output, as there are so-called "new style" CGA's with the 90 degree traces.

I kinda like the 90 degree traces better.

@gloriouscow The electrons need to slow down to make those sharp turns so the newer card is faster.

@gloriouscow Weird isn't it - almost all of the vias are in the same place; so it's not like they've completely relaid it out.
