Neat trick!  I made a slight modification to visually take advantage of the
5-pixel overlap.

So the RESP0/1 strobes are 1 cycle (3 pixels) apart, in reverse order...

Wonder if some insane programmer out there has used the JSR trick in
conjunction with an actual jump to a subroutine... and then re-strobed
RESP0/1 upon RTS along with RESM0/1. :)
