DEC RF08/RS08 module placement info

Hi all --

In addition to the 11/45 project I'm also working on restoring an RF08/RS08
fixed head disk/controller (in the vain hopes of one day running TSS/8 on
my PDP-8/I).  I have the power supply repaired and running and I'm getting
ready to power the logic up (the disc itself will be a project all its own,
once it arrives).

I'd like to double-check that all the flip chips are in their right places;
I have no cause to think they've been shuffled around but I want to be
sure.  The engineering docs have detailed schematics but no placement chart
for the modules themselves.  Given enough time with the schematics I could
derive this chart but I'm saving that as a last resort.  So, two
possibilities here:

1) Does anyone know of a document I've overlooked that includes module
placement?
2) Can someone with an RF08 and/or RS08 take a few detailed pictures of the
logic (from the handle side, of course) so I can compare?  (Note: the
available RF08/RS08 pictures on the 'net are of the unit currently in my
possession, so are not useful in this regard!)

Thanks!
- Josh
