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? Anyone tried to get
these things to run?
