I was reading the
List of All Lisa Software thread and its
Google Sheet, which subsequently links to a PDF titled "
The People Behind the Lisa's Development" from 1997.
In section X.9, the author reserves space for the people who manufactured the Lisa at Apple's Carrollton, Texas facility. He did not know their names when the PDF was made, and his final date of manufacture is off by one year ('85 vs. '84), but he correctly mentions that some of those remaining team members signed the inside of the very last Lisa's top panel. Seems a very Apple-like thing to do
John Woodall of VintageMicros had mentioned this signed panel to me previously and kindly shared a photo of it. Attached here, with his permission.
