Sega SF-7000 Super Control Stationhttp://www.trademe.co.nz/computers/vint ... 269850.htm
Listed by a friend of mine. Looks like it is in good, working condition and comes with a few disks. Possible problem with the RS232C port, although there isn't really any software around that uses it so not a major. A nice piece of Sega and NZ computing history.
You will need a Sega SC-3000 to use it though. That's handy, because he has one of those herehttp://www.trademe.co.nz/computers/vint ... 262324.htm
That's a nice collection too, and comes with a boxed SR-1000 data recorder, a SJ-200 joystick, SJ-300 joystick, and tapes and carts.
