Well, since it was such an easy job, I took a chance and replaced the two suspicious 7805 voltage regulators. The terminal works just fine now!

I'm sure there are other marginal components that will need to be replaced, so the restoration is not yet complete until I'm confident I'm not stressing the new 7805s too much. -Seth -- Seth Morabito s...@loomcom.com
