=== Multi-Adaptor Cable for External Floppies / HxC emulator ===
[[Image:Floppy_Cable.png|800px|centre]]
=== Adaptor Cable for Internal Floppies / HxC emulator ===
This cable assumes that the drive has been set to DS0 / ID0 and provides a ready signal. For the HxC not a problem, just a simple jumper setting, for floppies this may involve making some mods to the drive.

I've shown the cable from several views to highlight the fact that the connectors don't face the same way on the cable.
First crimp the 26way connector as shown in the diagram. Then split the first 6 wires starting from the side of the red wire. These 6 wires need to be shifted 2 cavities further over before being crimped into the 36way connector. Wire 26 goes directly to pin 34 of the floppy connector. Make sure the keyways / orientation slots of both connectors are as shown in the diagram. The cable needs no bridges, switches or anything else. When you are finished, you should have a cable looking something like this:

===Issues ===================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.
