Quick question: I've been cleaning out and repairing an HP5061 supply 
for a 1000 computer. However I didn't take a picture of the 4 boards 
when I pulled them and I want to make sure they go in the right places.

 From the manual (page 99 of 92851-90001_Sections-IXB_Mar-1981.pdf) the 
slots are labeled A6-J1 through A6-J5. Does this mean that:

J1 is the
J5 is the control board (A3A5)
J4 is a jumper board for +12 adjustments
J3 is unused (battery backup boards)
J2 is the inverter board (A3A2)
J1 is the pre-regulator board (A3A1)

Seems right but I know how bad things can go :-)
