I'm presently conducting an investigation related to a patent infringement action. I am trying to locate as much information (by way of original NeXT documents) as possible about the hardware design of the original NeXT Cube (i.e., the '030 motherboard version). I have seen reference here and elsewhere to certain manuals (e.g., a NeXT Hardware Repair Guide) that might provide schematics or block diagrams for the system. I am willing to either pay a fair price or pay for copying (and shipping and handling) of anything that could possibly help (so long as it relates to the hardware design).
Please contact me via private message if you have anything that could help.
