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:
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 :-)
Those are correct. I just pulled the cover off my (working) 1000 M-Series
that has a later model supply (5061-6630 date code 2601) but has the same
motherboard as yours (5061-1371). J1, J2, and J5 are as above --
Preregulator (5061-3457), Inverter (5061-3454), and Control (5061-6627). I
have the power fail option, so J3 is the Battery Charge card (5061-1348)
and J4 is the Battery Backup card (5061-1349).
