Looking for AMP / TE coaxial connectors - Memorex 651 drive

It  is from the AMP M series connector family used in the data cable for the IBM 2311/2314 and PCM equivalents including double density like the ISS 715 (RP03?).  So some of the parts strippers should have lots.  

Using coax at the FDD data rate was overkill so unless you want to preserve the connector for historical purposes u should be able to push out and then remove the pins and connect the wires to whatever connector suits u - flat cable connector for the control signal cable and whatever works for the three coaxes  (coax to twisted pair should work).

Subject: Looking for AMP / TE coaxial connectors - Memorex 651 drive


I am about to start with the project to archive disks from the Incoterm system.

This system makes use of the Memorex 651 drive which is somewhat odd. It has 64 tracks,is hard sectored with 32 sectors and spins at 375 rpm.

But I do have the drive which hopefully still is working. However the interface connector is nothing like I seen on a floppy drive before.


It is a AMP 202515-1 housing. The mating 202516-1 which I need is still in production and available for purchase from Mouser. The small coaxial connectors on the other hand has a minimum order of 1000 units and costs 10 euros each...


Does anyone know of a source selling something like three coaxial connectors like this at decent price?

Or maybe a suggestion for another connector that could be modified into fit somehow? Potentially using glue to fixate it.

Of course the last resort is to just solder some wires directly onto the drive PCB, but if there is a nice solution I try that first.
