Inspired by this recent thread: What do you have outside of PCE? - which is dealing with games, here is a thread to state which retro console systems you own.
For the sake of this post, retro is being defined as nothing after the sixth generation of consoles (Dreamcast, PlayStation 2, GameCube, Xbox).
I'll get things started:
[ul][li]NEC PC Engine (with CD-ROM2 unit and IFU-30)[/li][li]Sega Mega Drive II[/li][li]Sega Saturn[/li][li]Super Nintendo[/li][li]Nintendo 64[/li][li]Neo Geo AES[/li][li]Neo Geo Pocket Color[/li][li]Xbox[/li][li]Playstation 2[/li][li]Various arcade PCB's[/li][/ul]
I don't have all that many but the list will continue to grow. Next on my list will be a Master System, Nes and a Dreamcast. I try to only collect consoles that I will actually play, which will always keep my list on the shorter side. Typically, I only buy boxed consoles, as complete as possible and in great condition, another reason why my list is rather short atm.
