* Next thing is to leave at 20cms away from the PCB edge connector and then clamp the 34 way IDC Male connector onto it â the [[Media:Cpcdisk.jpgâ |Connection Pin Numbers ]] are all the same as CPC 664 / 6128. Making sure that the arrow on the 34 way IDC connector is clamp on from the red strip. Now you have a option to either cut the 34 pin PCB edge connector off completely (as I prefer) or leave it with 34 way IDC Male connector, making it multi-choice 3.5" disc drive to use on CPC 464 or 664 / 6128. <BR>
