Thanks Dennis and Gene.  That did the trick. I tried to do that but it seemed all I changed was view but with your suggestions I found the right button and am printing one of the odd pieces right now. Finally I can have enclosures for all these boards I run just sitting on top of the

It seems a bit odd that a power supply from someone like DEC of that era would be designed to depend so critically on the absolute value of a rail used for startup purposes. The output of the replacement 7812 varying between 12.2V and 12.4V suggest that the 7812 itself could be faulty. Or
