Now that's a collection I would love to have. The Xbox 360 is my favourite modern console. I have an Xbox 360 slim 4gb E RGH ( one of the new ones that looks like the Xbox one), A glossy 250gb trinity and a flashed Elite Jasper.
Well, it's not a console, but still it's the rarest thing i own: It's a Tektronix XN11 In working order. Sadly i don't have either a screen, the keyboard/mouse (proprietary) so i can't use it. Ah, the glory of the Embedded 386 processor!
Older IBM keyboards use that RJ45 connection, perhaps try one of those, also old terminals, I have some 80186 military gear that uses them. and depending on the pin count on that display port, probably EGA/CGA monitor.
Monitor is surely EGA/CGA, but i don't want to try the one i have directly because of the risk of shorting something if the pins aren't a 100% match. Also the socket isn't RJ45, it's the same cutting but there are eight straight pins coming right from the back of the connector.
An Ocarina of Time 3D EU demo cartridge . I guess Paper Mario: The Thousand Year Door PAL version is a bit rare?
This complete Mass Effect special edition cost me an arm and a leg... more expensive than any console I have bought. Plus maybe a couple of beta builds which I am not allowed to talk about openly.
I would say my CIB N64 JUSCO with a Sealed N64DD randnet (with the shipping box including the N64 smoke grey console)
Not sure if Suikoden 2 is the rarest thing I have (the only other one would be my Pikachu N64, at least that I can think of), but it's certainly the best value. [video=youtube_share;5uNkQFrsW-w]http://youtu.be/5uNkQFrsW-w[/video]
Diamond Edge 3D 3400 series. The high end model is really hard to come by. Got the whole shebang for $50; all of the games, accesories, original drivers, everything except Virtua Cop. This isn't my picture (the one I had I posed on this forum, but it disappeared now), and it's in my closet atm, so I don't feel like digging it up. Shogun.
I guess my rarest things now would be: N64DD (loose) + All Mario Artist w/accesories, F-Zero X Expansion Kit, SimCity 64, Doshin 1 - all CIB Panasonic Q (CIB) + extra Panasonic gamecube controller + Panasonic Q GB Player Red Twin Famicom (CIB) Gameboy Light (CIB) I know the last 2 are not rare at all but I love them and it was a bit hard to get them being in Uruguay. And the best thing is, all these consoles came from other board members Pictures: DSCN1084 by Tchoin, on Flickr P1030709 by Tchoin, on Flickr P1030704 by Tchoin, on Flickr P1040117 by Tchoin, on Flickr DSCN1202 by Tchoin, on Flickr DSCN1193 by Tchoin, on Flickr Gameboy Light by Tchoin, on Flickr Gameboy Light by Tchoin, on Flickr Gameboy Light by Tchoin, on Flickr
Isn't that the PC video card that played Saturn games (or ports of them) with quadrangle polygons instead of triangle polygons? Nice.
Rarest thing I own must be my sega mega drive booster pack . A double game pack that came in a paint tin along with a watch and some sweets
I... did not even know that "genre" was a thing. Nice! Rarest thing I own... uh... Maybe my Forte VFX-1 VR set? Runner-up would be a Gizmondo (actually two, but only one is in working condition). Nothing too exciting.
Nothing special, but I have a mint Japanese Virtual Boy. I'm currently "seeking out" a lot of things though. Most notably, anything related to Super Mario Sunshine. I have a reddit thread about it lol
Only 2 things :c A PlayStation 1 Debugging station (PAL) the 2nd ever imported to Iceland so it would be extremely valuable here and then I have a SCPH-7002 which I've never seen before here in Iceland, internationally it may not be rare but in my country it indeed impossible to get. but also I have probably the only SCPH-1001 PS1 in Iceland. got it from a friend in USA.
