Tom,

Thanks very much for the information and the photos.  Those are some great ideas.  Having one or more permanent loop supplies is definitely on my wish list.  I am working on a dedicated radio shack which I hope to have nearly finished in the next few months.  I want to have ability to connect my working machines and be able to connect "new" machines as I work on them.  There was an HD3030 that came up on eBay recently but I didn't get it.
