There's a computer museum trying to get off the ground in Auckland, Techvana. At the moment they're trying to raise funds to open to the public.
I stopped by the other day to help unpack/setup and the collection they have on display is impressive. I noticed Atari 2600, Apple II, Mac (of all shapes and sizes), Commodore 64/Vic-20, Amiga, Sun boxes, etc etc (over 1000 pieces). It was a great trip down memory lane.
They're having an open night tomorrow (Thursday 23rd Oct) so you can have a look at the concept and ask questions about investing etc.
Worth a look, it'd be great to see something like this stick around
