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?
