Tempest project complete

Tempest is finally working steadily. Game worked intermittently, but then constantly reset.

Molex headers at interconnect, on both boards, replaced with square pin type. All connector pins replaced with Trifurcon type. Bad solder joint seemed to be the issue, but connector replacement is cheap insurance.

I wanted to add a fan, without adding any holes. Although not the best placement, this 12v fan is attached to the monitor frame with zip ties. Very light and so quiet you can't hear it.

Fan is plugged in to the 12v and ground test points on the ARII. A supplemental ground wire connects the ARII to the Main PCB.

At this point, black stenciled areas are complete. Backbox surround pieces were remade out of 3/4" MDF. Must note that original pieces were closer to 5/8". They were attached to box, using carpenters glue, with pin nails to hold in place. 16ga finish nails were used in the end joints.
