Thanks, Tom! This is exactly the info I needed. Very helpful.
I will go through all of this and keep my fingers crossed. The 200-2 is missing the main power cord to the control panel, so I am hoping I can use some of its parts (bulbs, missing buttons, terminator plugs, etc) to get the 100 spruced-up and going. I think a friend has a sync generator… anyhoo, fun project.
