Any one know what this mod isOk +2b with a mod anyone know what it is and why its there and if its worth removing cheers [img]http://i.imgur.com/p5IG6Ec.jpg[/img]
The PCB Version is Z70833 Issue 1, and there is no additional caps on the Z80, I have replaced the wire from R45 to the chip as it was degraded and there was part of the resistor still sticking out of the board. So I take its best just to leave it as is.
