Quote from: pelrun on 06:35, 27 May 19Jumpers aren't needed because it's essentially hard-coded cable select, with only one drive select signal available on each connector.The external connector has an inverted /DRV1 signal to the internal one, so when the internal drive is selected the external is disabled and vice versa.

Changing that seems a lot easier than monkeying with the cable.Found a decent photo here: http://www.cpcwiki.eu/forum/hardware-related/fixing-floppy-drives/msg144099/#msg144099
