Here is a link of some photos I took some hurry during the evening.

Does it make any sense to you? There were same cables that was obscuring
the view which were hard to get out of the way. Please tell me if you can
make any sense out of it.
A quick check of the drawings didn?t reveal any module placement drawing. I
will check in more detail tomorrow.

Thanks! That will be very helpful!
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!)
I have a RF08 / RS08 combo. It was connected to a PDP-8/L, but the
cabinet with the DW08 was missing.
I can take a bunch of pictures next weekend.
I have a vague idea that I have a bunch of docs with the unit. Double
ledger size or around A2. I will have a look.
Would be very interesting to read your story when
repairing it!
I'm going to try to write about it, we'll see how good I am about keeping
up. Still slowly writing things up about the 11/70 from earlier this year
and I'm behind on just about everything. I imagine getting an actual
physical disk working is going to be an unlikely prospect, my plan is to
develop some hardware to emulate one or more RS08 drives, eventually. But
I want to try the real thing first :).
