- IT types – what is this hard drive connector?
This is an adapter tray for an AKAI MPC 1000 and 2500 hard drive. These MPCs are 15 years old now and this (official) part is no longer available. A third party part is available but it’s $50+postage+VAT+import handling, so probably close to £100.
The adapter part has 50 pins which plug into the MPC and a 44 pin IDE connector which you plug a 2.5 inch hard drive into.
This is a long shot – does anyone recognise or have an idea as to what the 50 pin connector is. If it’s something standard then I might be able to source an adapter.

I don’t actually have one, so I’m only going by what is on the internet! I could disassemble my MPC 1000 to see what the pins are on the actual machine.
Here’s a link to an image showing the connector head-on
I don’t think it’s SCSI. Could a SCSI to IDE converter be that small?

Yeah, the drive side looks like a 2.5″ IDE (parallel ATA) connector.
The board side of the interposer could be literally anything, it’s whatever the manufacturers wanted it to be. It’s not necessarily any sort of standard at all and IME is highly likely not to be. It doesn’t have to connect to a common component like a hard disk, it’s a bespoke part for that particular device. I’ve seen this sort of thing loads of times in laptops, and I’ve never seen two the same. My 17″ Dell can take two hard drives and the interposers for each drive are completely different from each other.
Plus, physical connections aside, who only knows what sort of electrickery is going on on the PCB.Posted 2 months agodeadkennySubscriber
50 pin would be 2.5″ IDE (counting the pins on my spare 2.5″ drive I have here).
Edit: ah, looks like 50 pin is the drive side for a 2.5″ and the external side is some proprietary connector to fit to the device.
What you really need is a long winded video showing how to fit one of these with some funky music 😀Posted 2 months ago
Centronics doesn’t have angled edges on the female connector (ie, on the caddy), it’s the surrounding shielding. The sides of the ‘tongue’ should be straight. The mating side does look like Centronics but I don’t think it is, the height of the gap doesn’t look deep enough. You might be right though, it’s bad to tell.
SCSI-1 did actually use a Centronics connector – I’ve half a memory that I’ve seen something very similar to that video on the back of very old hot-swap server hard drives – so there’s a logic here that could suggest it’s some sort of converter, but there’s no circuitry on the interposer that I can see so that feels unlikely.
So if it is a Centronics plug but not SCSI, then I’m not aware of any sort of standard ATA > Centronics interposer. If you were to rig something that fitted physically you’d still have the issue of how it was wired electrically.Posted 2 months ago
Thanks for everyone’s input.
Here’s a link to the 3rd party connector:
As Cougar wrote, there is no circuitry or components on the converter board, it’s just tracks connecting the pins. I could probably make my own for a fiver if I know what the 50 pin connector is! 🙂
Might be time to buy just some connectors and then see which fit. Disassembling the MPC is easy, I’ve done it already to fix the pads and I’ve got to do it this weekend to solder some new switches in.Posted 2 months ago
Nerd… my suggestion would be to take the MPC apart and have a good look at the mating part, take photos, post on here etc… some scale would make it easier to identify.
My guess is it was used in the unit as the connector is quite robust and can be used for blind mating… I think it is probably a coincidence that it was also used for SCSI.
The PCB is, if you are lucky, just a pin to pin but I wouldn’t be that surprised if it wasn’t 1 to 1, and some tracks were crossed over etc…Posted 2 months ago
Thread update! Thanks to a very helpful post on the MPC-forums by a nice German man, it turns out that the connector is one of these:
Thats a 3M Mini Delta Ribbon (MDR) connector.
I think I can make an adapter from 2 connectors and some ribbon cable.Posted 1 month ago
