BBU, short for the Bob Bailey Unit, combines a whole lot of functions which were handled by individual chips (PLA's) in earlier Macs.
One of the issues you had before with the display being garbled,, well, the BBU handles memory access for the video, so the sypmtoms make an bit more sense now seeing the state of your BBU!

Original Macintosh team member Andy Hertzfeld credited Bailey and Brian Howard with engineering the best of the early Macintosh models"
