Interesting. We also have a RF08 / RS08 combo. It came with two PDP-8/L machines. I am not sure if both PDP-8/L CPUs were connected to the RF08 simultaneously or how it was connected once upon a time since all cabling has been removed prior to us getting to it. The front panel look exactly the same. The drive and controller sits in a full height cabinet with the drive in the middle and the controller at the top. What is the plan with your RF08/ RS08? Is it possible to get it complete or is just parts? The RS08 seems to be a DF32 on steroids. The question is if it would be possible to have our unit working some day?
