Mac Plus with funky analog board and ROM errors / Sad Mac

Picked up this Macintosh Plus for $15(!) at a local e-waste recycler, but it's got a couple issues as you can see in this video. I've tried reseating the ROM's and RAM sticks, but it didn't help - any suggestions or ideas on how I can resolve either / both issues seen here would be much appreciated!
