I have recently received a CPC6128 and had the problems to connect 2x3,5" drives to the CPC (internally and externally). The main problem was, that i've could not find detailed informations about the wireing and the signals (even here on CPCWIKI.EU) This is my contribution to this issue. I will add the wireing for the DDI-1 soon.

This cables work for drive which are jumpered as drive 1 or DS1. This is normally the default selection on drive delivery. Also make sure you find a drive which has the possibility to generate a ready signal instead of a disc change signal.

If you intend to use a HD drive, make sure to close the HD detection hole on your disk. </pre>
