The idea with these pouzzles was to let everyone play with them for a week and then publish a/the solution.

Ok, you blew it.
so here is "my" solution

insert the macro SETCOUNT at ;;here

Delay:
;; here
      SETCOUNT 
loop: djnz r7,loop
      djnz r6,loop
      ret

SETCOUNT   macro
           LOCAL NoInc
           mov   a,r7
           jz    NoInc
           inc   r6
NoInc:
           endm

Since this resulted in a totally different action than the intended I will gladly be a contributor if a "puzzle management" is set up, but otherwise, stop.

Since this is one of the areas where I seem to have a blind spot (can never remember right off the bat what to do), I made a macro to do it.
