Hi all,

I recently re-discovered the PDP 11 . I had a chance to use one around 1995 (I don't remember which version exactly) . I found a lot and a lot of documentation , and I start to learn Unibus, reading the "Unibus Specification" .
I understood that each Unibus lines should start and end by a terminator.
It seems that in slot N°1 we find the processor and in others we find some other board like memories, drivers etc. In the last slot we find a terminator (M9302 ?)
But I didn't see the first terminator (Near the slot 1).
Where is the first Unibus Terminator ?

Thanks for helping.
