I'm still in the process of assessing what the condition is and taking photos, but basically I have the main unit, the mini expander with the 2 game controllers (boxed, box is in average condition), the cassette recorder, the simplified instruction cards and guide to home computing (the manual) - these books are in quite good condition, a 16k memory cartridge, an application (game?) cartridge called Utopia and an application cartridge called FinForm. The plastic of the main unit is quite discoloured (as beige plastic usually is), but I fired it up this afternoon and it still goes. The RF switch (plugs into the tv and switches from tv to computer) that I have is not the original, it is from a SEGA, and seems to have loose connections, so I will have to look into soldering it or something.
I'll get some pictures up in the next few days, and maybe put it up on Trademe for you all to fight over
