I'd like to reverse the output pulse sequence order of a 6 output
Johnson (walking-ring) counter constructed from three 7474 D flipflops
which are wired as Q1 to D2, Q2 to D3, Qbar3 to D1. This produces six
outputs spaced 60 degrees apart with a sequence of Q1, Q2, Q3, Qbar1,
Qbar2, Qbar3. I'd like to be able to reverse this output sequence
with a switch. A 6PDT switch could be used to simply change what
flipflop output is connected to my actual output. I was hoping though
that there is a way to use a three pole switch instead (easier to come
by in a toggle style) and somehow change the connections of the
various D inputs and Q or Qbar outputs.
