Hello NeXT Community: I went ahead and purchased the original NeXT Factory Manual and Schematic for the early NeXT 4000 Monitor and at $75 , I have donated it to the NeXT Community and uploaded it in PDF form to our archive, , enjoy ! It bought from an original NeXT engineer , I hope they find more in the garage clean out lol... It is good for us. Here is the link:
