Another solution would be to store the previous sequence of screen
addresses used for the wire-frame and do a quick
        
        LD (stack+1),SP
        LD SP,nn
        POP BC
loop    POP HL
        LD (HL),A
        DJNZ loop
stack   LD SP,nn

(or something more elboate if B>256 - from the top of my head)

My guess is that he doesn't even know.....
