Hello!
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...
https://www.mouser.se/ProductDetail/TE-Connectivity/201146-2/?qs=DuOyNqEZh0…
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.

That connector looks a bit similar to the Winchester MRACs apart from the addition of
some
larger holes and pins for the coax connectors. Your second link didn't work for me
but
looking at the first pic, perhaps you could bodge something up out of a piece of K&S
brass
rod and tubing, with some tubing spacer from a suitable dia body eg. a ballpoint pen.
For the connector body, it could be 3d printed, or make a paper rubbing and drill a block
of plastic, or simply fix the makeshift pins in then cut spacing strips of plastic to
slip
through the rows and then bind and cover with epoxy.
I made a quick stopgap power connector for testing an Amiga 500 by soldering the leads
of a discarded rack server power supply to 5 small nails, worked just fine.

A small bit of info that may (or may not) interest you:
The strange female connector soldered on pcb of any amiga computer can
be xchanged by a DIN-8 PCB female connector. Just unsolder the square
beast, and solder the common DIN-8.
I have to do this in mostly all power-supply-less amigas I get in Brazil :(
Maybe you're interested in this small piece of info :)

A quick Internet search returns this link:
<http://www.buy-components.com/components/te-connectivity-amp/201146-2.html>
and they both claim to have this part in stock and sell it in arbitrary
quantities, although they do not seem to do retail sales. You might try
contacting them regardless outlining what your problem is and they might
be willing to help.
NB I have nothing to do with them; it's just a generic attempt to help.

Well. I am a bit sceptical against all those "components vendors" that
popups when googling. Usually they actually don't have the component. If
they had it why bother about inquiry? Why not just sell it? Anyway there
are some evidence that buy-components is a scam:
http://www.ripoffreport.com/reports/buy-components/internet/buy-components-…
https://www.trustpilot.com/review/buy-components.com
There seem to be very few real surplus sellers out there. I have dealt with
www.electronicsurplus.com and www.surplussales.com earlier without any
problem. They are a companies that actually sell stuff.. Unfortunately they
don't have it.

What they do deal with is that when they get a request (such as when you
submit your request), they will send out the request if they don't stock
the parts to a network of associates.? They will respond if they have
it.? In my friends case, they've been in the business for 40 years, and
one of the brothers selling IC's and the like for nearly 50.
If you hit any one of them, you will likely hit all of them, since the
request you send in is shared.
I always send my business thru my friend, to be sure I don't have a
problem, but others probably have not had the connections like that.
For this part, by the way, you might try electromavin.? He's been buying
parts for at least 40 years I know of, and would probably know your
part, and if he doesn't have it would be an excellent source to hit the
network of connector parts vendors.
The site and contact for him is here
http://www.mavin.com/
A scary thing, he may be retiring, as are a lot of these, and the stocks
will likely not be saved from the final trip to the gold scrappers.?
(who sold them a lot of the parts in the first place).
I know he is currently selling parts, as a friend is building up a lot
of HP test equipment test cable sets for a number of instruments he is
bringing up, and the sort of winchester looking connector you have
there, he has in stock.? Also the Canon d-sub body stuff.
Thanks

It is a AMP 202515-1 housing.
I buy some M-style connector housings from Newark in
the US,
and they sell them in single quantity.
I think Newark has EU branches as well. This housing is a
smaller version from the same series.

Isn't Element 14 the UK version of Newark?

I've got some old evaluation/development kits available for adoption.
None is really anciet, but all offered as a unit to a good home.
1 Rabbit 2000 devkit with CD-ROM, wall wart and serial dongle
2 Digilent UNO Pic32 dev board
1 TI ez430-F2013 (MSP430) devkit (just small USB gizmo) with CD
None has been used much--purchased mostly to see what was out there 15
or so years ago...
Anyone want this stuff? You can have it for shipping, otherwise it
joins the big eCycle pile.

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).

What parts strippers is this? Did these drives use coax connectors as well?
If someone see a used M-series with coax connector please save it! I am
very interested in used parts as well.

I don't want to replace the current connector since the mating connector in
the drive controller needs it. I just want something proper if possible to
use when dumping the disks. But I don't want to spend a fortune of course.
If not possible I simply solder wires to the relevant points on the drive
circuit board.

Personally I can?t recommend any company selling used parts stripped from surplus
equipment but I recall several being discussed in this thread.
My recollection in the 2311 and 2314 class disk drives from IBM, Memorex, ISS (sold by
Itel and Telex), Calcomp, CDC, Ampex, etc all used M series for both the data and control
cables. The data cables were hermaphroditic with two or three coax connector receptacles
and a number of sockets at each end mating to the corresponding connectors in the drive
and controller. So what u really want to find is a data cable from these very old drives
(or at least one half of one) and strip out the sockets.
It maybe the 651 used the same connector block as the 2314 class data cables; I doubt if
Memorex had the money to pay AMP for a custom block so they just used the connector block
that was in their 2311/2314 line ? IBM paid AMP for that block J
Good luck.
