External Floppy Cable

Another FB conversation prompted this when somebody asked about connecting the FDD part of the CosmosEx to the external floppy port, to give a B: drive.

So guess what I'm making today:

I used an existing external enclosure to get the pin mappings I needed looking at the front of the plug, as I couldn't disassemble it:

And then reversed it:

As I would be working from the back of the plug.

I then clamped a new 34 Pin IDC connector on to allow me to buzz out the wires to the plug as per my diagrams:

Once I had the 14 wires I needed I trimmed the rest off and began to get my assembly going:

The end result being:

Hopefully the pinouts and will help somebody wanting to do the same as me.

Make sure you buzz everything out before assembling to make sure all the connections are good, I had one bad solder joint and a pair of wires transposed.

Happily it's all connected up to my MSTE and CosmosEx and working a treat :)

Very nice. Ive not built one for like 20+ years.. *somewhere* I have a 5.25" proper floppy drive.. That Pinout must go back to "paper days" :lol:

@exxos I've had the parts for years, I bought the din connector from you, god knows how long ago.

Connecting up the CosmosEx as a 2nd floppy was the nudge I needed to make it.
