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!
