Actually, there is a scanned/PDF version of the MPC60 Service Manual and Schematic Diagrams an PC Boards in the Yahoogroups MPC60 group files section.
The PCB layout pages in that version are hard to read, as the original uses different shades of grey and red to show boath sides of the double sided PCBs in the one picture, and the scanned version is in low resolution black and white.
So, I would check out the MPC60 version, set what it is you want from it, as it seems pretty similar to the MPC60II PCB's, and I could scan just those pages as higher resolution colour version so you can see what is going on better.
Let me know if you want anything scanned from the MPC60II docs, after you check out the MPC60 docs.
