Fully soldered and ready to see it’s first electrons. I did leave the expansion connector off for now, it’s not essential for operation and leaving it off offers the ability to scope the bus at it’s location.

The only surprise so far, is that the large heat sink extends a tiny bit beyond the edge of the board. Reviewing pictures of the original shows the same thing, so all is well. I was a bit worried about how the large 5 volt regulator and heat sink would go in, but no issues at all. I put a little thermal grease between the regulator and the heat sink and bolted it in with some 6-32 by 3/8″ screws I found at Home Depot.

I’m not real happy with my decoupling cap selection, since they are much smaller than the original. I’ll probably replace them at some point.

First test will be of the power supply without ICs installed. That will take place tomorrow.
