Is the z80's MREQ line available to peripherals? I forget whether
that's active during refresh cycles but it would probably give the

As a quick mea culpa, there was a bug in my code that means the second
set of figures I had were wrong. I'm back to an average 10% and up to
15% worse than Adrian.

Sadly I'm already doing that and still doing a lot worse than you. At
