PDP8/S internals

[Gordon JC Pearce]

Hi there,
   Perhaps someone who is a little more familiar with the innards of the 
PDP8/Ses can answer this...

Are the individual flip-flops arranged like a shift register or a set of 
latches?  In other words, when data is being clocked into a register, 
does a bit get put into (say) AC0 then bumped along until it eventually 
ends up in AC11, or are all the D lines of the flip-flops connected 
together, with each one being clocked in turn?

Gordon.
