I just wonder how many Poly's are still around in the country??? I don't think I have ever seen any mention in collections that people have listed publicly on the internet. I'd call it as a best computer in a collection item.
It's possible one of the double disk units in the room goes with the Poly's also. I just remember the disk units being quite big and separate and I think networked with the computers. They were 8 1/2" disks. I guess the guy on trademe with the midget2 handle would know.
It's a pity they don't look too well looked after and I'd be surprised if many still work in contrast to the Commodore Museum where they all did, apart from maybe some of the Pets. However there's some pretty rare looking items in the listing, at least for NZ and with all the styles and designs that only the 80s could produce.
