Bushface did a neat and tidy version of the tree. It also corrects some errors from the pdf and contains extra information like building costs. It prints out onto a single sheet of A4 and is very readable. Email him at rff@tesco.net with the subject line VI Tech Tree.

He had posted this over at the official forums a while ago. The tree really is worth a look. He also has some maps of the VI and MTW provinces complete with trade information. Again worth a look.
