M-Systems had a series of SCSI-SSDs (FFD-35 and FFD-350) that looked pretty similar inside in the early 2000s. The capacity of the FFD-series varied a lot with 128MiB - 38GiB depending on the model. The type of controller was also depending on the model but often based around the IBM PPC405 CPU. M-Systems was bought by SanDisk as well.
That pin 7 power is sth I had no idea it existed. Smarter every day. As always amazing video despite the audio, just a heads up at the beginning would be nice so that we don't wonder if we have an issue.
I remember years ago working with something like this, is was basically a HBA and a SSD raid drive all in one for fast SSD storage. it does look like is it a similar device that has a raid array built in.
I never knew that some boards could supply 5V on pin 7 of the SATA connector. Are 3 ground pins really necessary in the first place? How does the short circuit detection circuit work. Can you show a board that has this?
The extra ground pins make the signalling cleaner on some devices. For serial interconnects like SATA, having the ground pulse couple with the send signal reduces crosstalk.
Another very interesting video! There seems to be some microphone problem, audio is kind of off, like it would be clipping on recording or something, but it's normaly loud in the video.
Wow, I have a bunch of those SATADOMs and I had no idea about the pin7 trick, going to try that later instead of faffing with yet another cable in some NUC type micro-pc's. Also though it's "Disk On Module" not 'Motherboard' for the acronym.
@PlaywithJunk a fair and justified warning, I will of course ohm some things out, and consider some form of current limiting to keep the magic smoke inside. I just had no inkling that some manufacturers even considered to do that, to the signal cable of all things. But I guess if all they needed was one voltage rail and 3 shields is too redundant. 🤷 Why not.
@@Roobotics The pin7 power feature should be mentioned in the datasheet of the DOM. It seems they were proud if that invention... I made an adapter with two SATA connectors from old PC boards. One connects normally to the PC that has no Pin7 power and the other is wired for the DOM with pin7 gounig to a 5V power supply. Since I'm the only one who uses that, no protection circuit required 🙂
@PlaywithJunk that's a good idea also. In my case I've already bought a bunch of specialty right angle male/female adapter boards that are luckily bare PCB types, so I'm either going to lift the exposed pin7, or make them proper custom cables, only catch is I have to do it 10 times in a row. 🫠
I wish more NVME M.2 drives supported activity indication- both of my Samsung ones do buy my high end WD one doesn't. The Samsung ones even have fault indication through the activity line.
27:00 I need one of those type drives for a WindowsCE workstation out of a Police Cruiser. The one that was in it only 512mb. And it needs reflashed or replaced. It won't load or boot the OS hangs with a blue screen.
Maybe not that mans as you may think. This board needs to be very strong because of the many modules that plug in it. There is quite some force involved when adding or removing cards.
I think on the satadom the M probably stands for "module" rather than "mainboard". I have never seen any bame like satadom include the term "mainboard" in more than 40 years of working with computer hardware.

As a non technical person I always feel like I learn something watching your videos, great work as usual.
Is there a slight buzz on the audio?
Yes there's noise on the mic. Pherhaps a bad mic line in or something.
Yes. Some of the higher frequencies are clipping. I had to play with the equalizer because of mike issues.
Damn that's one thick PCB!
thickest board I've ever seen

9:46 looks like the internal intranet address used by Pliant.
As always it's fun to wade into things that would have been worth a fortune new.

Well, I thought audio is OK until I got the first complaints. I already ordered a new mike 🙂
I have those ITanium Cpus. Nice too see them on a channel. One of my first collection starters.
ALDI uses these epaper price labels but some supermarkets still use paper labels.
Is that a McKinley? Late 00s Itanium were solid chips. Cache for days. My last Integrity space heater died a few years back, should find another one.

Yeah I had some problems with the mike. Needed to equalize some frequencies. Maybe a bit too much. I guess I need a better mike....
@@PlaywithJunk Audio is just very low, I had my phone to full volume and when the outro played I nearly fell of my chair...
recorded 4 hours ago? crazy to see the correct date on the ipad
Yes it's still fresh... 🙂

Not sure if all SATA-DOMs support that pin-7 feature....

I made an adapter for a "normal" SATA mainboard... no problems to use the DOMs on Windows.
I wonder how many layers there are in the transition board? Sometimes this is indicated on the PCB.

11:02 Use Cons log_key to see log definitions
Maybe if you send this "log_ key" over serial it will give you a set of commands in response?

Yeah, you're right. Module makes more sense. I guess I confused that with LOM... Lan On Mainboard. (from HPE etc.)
I could have sworn that the HP Integrity rx6600 just came out… Time flies, I guess.
Everything after 1999 is "modern" stuff 🙂
And it wasn’t as good as the DEC Alpha…
I bought one of Intel's SSD's back in late 2008 so this is probably a very early second generation consumer drive?
the MCU in the E-paper shopping tags can be reprogrammed
And if this is the technology that play with junk is letting us see, imagine what kind of stuff he really has 😮
🙂 I only show you the best...

Something I didn't know until editing.... I was just watching the small camera screen.
@@PlaywithJunk Okay.
Itanium - Intel's biggest stupid mistake. Well, one of their biggest stupid mistakes.
Why stupid?
Because it was a flop. It wasn't compatible with existing software.
@@simontay4851it _was_ hardware compatible with existing software, it was really _slow_ when using the compatibility instructions.
