something similar to an assembly-level repair for the HP-85
may be found at:
	http://www.series80.org/PDFs/HP85-RepairCourse.pdf
This is guide designed to teach repair technicians how to service the
HP-85A and HP-85B Personal Computers.

For the HP-86 you can find the assembly-level repair manual at:
	http://www2.akso.de/files/series_80/Assembly_Level_Service_86B.pdf
but I think the quality of the scan leaves much to be desired.

Also you can find Tony's schematics for the 86B at:
