34-pin standard floppy to 26-pin Toshiba T3100e FDD plug

[TheGrungler]

Howdy all,

I'm in the process of repairing a T3100e I found on ebay recently, and in the process of getting things up and running, I obliterated the original floppy drive.

The short of it is it is completely and entirely unusable. It is currently a pile of fine dust in a ziploc bag in my closet. (this isn't true; I made it up. but it is entirely unusable.)

I decided I'd buy a new one, but lo and behold, the pinout is wildly different than the plug I need to connect to my system board. Below are the images of the back of the new drive and the cable I need to adapt to.


The keen eye will discover that these are not the same. As I am still pretty new to this, I call upon the advice of the forum members that have been on this website longer than I have been alive: have any of you done something like this before? I've spent a good while looking around at adapters, but all I've been able to find are posted here. I'm pretty sure that the end plugs I have will not fit, and I'm worried about the pinout from one end of the cable changing before it gets to the other end, destroying my new drive too.

I hate to ask so much based on so little, but if anyone here has any advice I would greatly appreciate it.

Thank you so much!

34 pin to 26 pin adaptors are available however some require modifications to the wiring. I use to have Compaq and Toshiba laptops that I replaced the drives on and remember it was pretty frustrating getting them working. Lots of pencil drawings to map them out.
Lots of information out there.

Fair enough. I would expect something like this to be too good to be true, then :// [apart from the fact it is amazon brandless slop]
The pinout on the board doesn't look too crazy, let's just hope that the pins on the drive itself aren't *entirely different*. I wonder if it would be easier to design and order a PCB for this, and if anyone's done it before. I would like to avoid programming an FPGA or something to handle signal conversion.

I've been digging around for a good while, and there have been no real updates. From what I can tell, there really aren't good commercial options for this. I can't seem to find any - *any* - of the components I need. Any information on this would be greatly appreciated. For now, I'll think about making the PCB myself.

I would try to make cable with a transition from 34 pins to 26 pins. Below is the list of signals for the 26-pin connector of the Toshiba 3100e.
