New pcb design for S-100 prototype board available

I've got photos of a good number of S-100 boards on my site which may be useful as a reference. Click on the "S-100" title of the S-100 machine section, or look at any specific machine and click on the installed boards. There are a few which have regulators in opposite corners (SSM CB processors for example), and a few which have refulators on opposite ends at the top (eg: Cromemco System support), but most boards have the regulators clustered together. What I find interesting is the number of boards where the regulators are positioned away from the end with the power supplies, with traces running around the outer edge of the board to carry unregulated power.
