Dev Saturns are just ordinary Saturns that have been modified - picked off the pile and shipped, pretty much.
The Saturn that I just mentioned (B50 serial) IS a Cross Products modified Saturn that comes with a CartDev - that's what's special about it, and why I'm surprised it has such a low number!
There was no special treatment of the consoles for development purposes by Sega - they were modified elsewhere.

I can confirm that S691XXXXXX, 6 digits with low numbers like less than 1000 or a little more, are actual dev/modified saturn. By 95-5183 Seiyo D. with 670-6924A Sega part number. That's not a coincidence for me as I can confirm that 6 dev saturn have this type of serials. External box (HST-0004) also have the same serial. I never saw a standard saturn with s691XXXXXX serial numbers.
So it could be a special run made by Seiyo and shipped to the dev manufacturer to modify this special run (?).

It is possible that they put the stickers on and sent it to Cross, yes. However, I can guarantee that not all consoles modified by Cross had S691 serials.

Your B50 is from a HST-3200 version maybe and could be earlier than the ones I have with S691 serial numbers, so yes, multiple runs used for dev afterwards. I am agree that dev saturn are stock saturn modified as you clearly see the case has been modified and not made for the additional card to fit in.

I've added a rudimentary search form on the db page, which you can use to narrow down the serials. Please report if you find any errors.
Interesting info about the Sx9x serials. On the pictures I have of the serials, none of them show any extra dev crap attached (maybe they were just removed, or they are on other parts of the machine you can't see on the photo). So I wouldn't know if the stuff in the db is from actual dev units or not. The only serial I have (not in the db yet) that's confirmed to come from a Psy-q dev box, is a standard B50 serial.
btw madroms: the 670-x number is not for the machines, its for the serial sticker. It's a print label ID.

Yes, the reason why the machines are the same as a retail unit, but could in theory have different innards, is that the sticker is just the last part applied. They could use parts that are months old... although sticking to the correct parts for the unit, of course! And then, naturally, it's perfectly feasible that they could use a special serial for the dev kits. Psygnosis gave them a serial number, too... which bears no relation to the actual serial number. If it's a dev kit, that's on the side... and I would have assumed that people would have given you a photo of that, too... considering you're asking for information! lol. Cross didn't give a unique serial number to the CartDev Saturns, though.
This is the exact reason why I always say that these consoles are NOT the dev kit. They're just modified stock Saturns... albeit modified for more than just playing imports, usually. The dev kit itself was the CartDev or the Psy-Q cartridge... in fact, the modified Saturn was an optional extra and they would work in a standard off-the-shelf Saturn.

Well, maybe I didn't ask at enough places. Or maybe I just didn't give nothing impressive back, so people don't feel like contributing (over 90% of the serials I got from periodically checking ebay and yahoo japan). Or maybe people just don't want to give out any information about custom hardware, due to the typical prototype hoarding mentality.
Once I finish with the DB page and upload all the pictures for the serials, I'll ask around elsewhere too.
Not sure where on the page would the pictures look good, though. I'm thinking of a hover thumbnail when you move the cursor over one row (like the popups at satakore.com), and a lightbox with the full image when you go and click on one row. I imagined the site to have inline thumbnails in an extra columns, but hovers seem to be the best way to not compromise the current layout which I like more.

Thanks, that fills up a lot of missing numbers I have.
Also, I've just checked the other Sx9x serial pics I have, and one of them has that extra cable visible too (I thought it was just some plastic junk stuck on the machine). What kind of cable is it, by the way?

No, I mean, what type of cable? like, mini-din, or d-sub, or what?

I'm guessing it's like this:

The IDC cable is for the NMI connector (cn10 I think on the motherboard of any stock saturn), and I believe it allowed you to reset components of the machine.
The back cable uses a video connector? Why the hell would they do that? They could've used any other standard, easier to find connector instead!

retro is the one to ask for dev stuff as he probably has a MORE complete set + docs than me I don't know myself what this cable is for.

Yes, the NMI cable is for interrupts for debugging, basically. The connector pads are there on any Saturn board, but the connectors won't have been soldered onto the board. It connects to the CartDev system.
The other cable isn't always present. I'm not quite sure what it does, but I think it has a video connector because it's a video cable. There's nothing in the manual I've got, but I don't think I have the complete CartDev manuals (just about the only one I don't have!) It could be for some kind of video capture system, perhaps? It certainly doesn't connect to the CartDev and I don't believe either cartridge for the CartDev will take it, either. Seems it'll only plug into the Saturn itself (pointless?) or another device. A look at the other end of the cable would reveal what the cable is doing, at least. Having said that, dismantling a CartDev is a bit fiddly, so I don't know that I'd recommend doing it just to discover a bit more about a cable!
Mick's picture is the Psygnosis-modified Saturn, which won't have either cable.
