Nice cleaning job!

The two damaged pads #10 and #11, with no track from them are unused by the HP-IL module. You may not need to put a finder on them.

The other pads are used (of course), including pad #9 that is named OD in the HIDS but is actually used for Dout to chain the HP-IL modules in the dual HP-IL module carrier HP82402A.
