I have one of these Dell DX9 drives sold by Amitek!
The cable, imho was badly put together which resulted in mine falling to bits
I still have everything so if I can fish out soonish, I will take some pictures of it.
From memory, there is a standard 23pin moulded end for the Amiga, terminating to a custom made board with the 23pin cable wires soldered onto pads. The board carries an IC chip and a few extra resistors etc.
When the cable broke! Some of the wires ripped off this board and I had no common reference to try and sort it out. So it has been useless for many years. When it worked! It did its job well, no software or drivers were required! it just worked as it should
EDIT: I am going to make this my mission! I realise now, if Amitek used an off the shelf GAL chip... then its obvious there has to be some kind of pinout schematic for it! Then maybe with luck somebody can trace all the lines and figure out where some of the wires go. I seem to recall at least 5 to 8 wires came adrift on one side... I would be stoked to get it all sorted and working again
