Him thanks, but JAE is not the slim CD addapter?

My problem is the 50 pin cable, jae to normal IDE40 i already have, but the connector in motherboard have 50 pin

OK I see, I didn't know such a thing existed.

Intel's D810EMO uses a 50 pin IDE connector for the secondary IDE channel, although they provide a cable.

Hi, i need help with a 50 pin IDE connector, im really lost where to find a cable, connector, becase i need to connect a slim cdrom. I search in ebay, aliexpress, etcetc

any advice is welcome, thanks!!!

Well, that's a strange connector. It says "40" right next to it, but it has 50 pins. As it is called "IDE2", there likely is an IDE1 connector too, possibly the one right below it. If that one is a 40-pin connector, you can use a continuity tester to find the standard IDE pins. Likely most pins except /CS1 and /CS2 are connected between IDE1 and IDE2. The remaining pins might be power pins. You can run a continuity test to the power supply connector to find out.

is this like a scsi 50 pin connector but with a smaller pitch ?
I've got one in my digital multia.
I tried to find a replacement, just in case, though haven't had any luck so far.

Take a look at this: https://www.elecbee.com/en-3338-2mm-pitch-2x2 … PxoC5TgQAvD_BwE
and here: https://www.sealevel.com/product/ca309-50-pin … e-22-in-length/ or here: https://www.amazon.com/Uxcell-a16031600ux0787 … 83152996&sr=8-3. You would have to make the adapter yourself thou (just to be clear).

Hey I recognise that board 😀 I have the same connector in this DigiPOS computer - this is on the riser that attaches to the mainboard with a PCISA connector.

I've derived pinouts for a couple of other devices and since I have this one to hand here's what I've found - I think it's basically 44-pin IDE shifted over. All entries with text are verified connections and the ??? ones are ones I'm not interested in verifying yet.
The riser PCB seems to be 4 layer with 5v and GND on the inner layers. Signal traces for this IDE connector only route on the back-side of the PCB since the floppy drive connections route through this connector on the top-side.

The extra pins just seem to be extra grounds and I can't see the remaining ones routing anywhere so the ones not connected to GND are probably N/C as they're not 5v.

It should be safe to buy a "Slim CD to 44pin IDE Adapter" and a 44-pin 2mm pitch cable. Either break off the tab on the socket or cut off the tab on the connector, so that you can fit the 44-pin IDE cable shifted off to the side so that pin 1 on the connector goes into pin 1 on the socket - I can confirm that pin1 on the socket is located by the silkscreening for "U1" at the bottom left of the socket.
Then the CD-audio can be run from the slim-cd adapter into the soundcard.
It should work, but I don't have the parts to test it and my DigiPOS isn't really operable right now, but now that the 5v and gnd pins are confirmed it should be safe to go ahead and test 😀

I have two motherboards from an Intel DOT station 2300 (https://www.youtube.com/watch?v=0sx26Yxt_r8) aka "pakito" M0810e that seems to be derived from the aforementioned D810EMO.
I have one of these DOT stations, but I never tried to add the IDE CD-ROM to it, it seems that it is possible to do it using the standard IDE connection configuring the drives as cable select.
This old page is in Spanish, but with the photographs it explains a lot. https://web.archive.org/web/20040608061458/ht … dide/hdide.html
For a Slim CD-ROM I've seen another mod using an adapter like this one (https://www.startech.com/en-eu/hdd/opt2ide), but I can't find it now.
