Hi, I've had a lot of interest in the collection, but my time is running short so I need to sell this whole collection, I've lowered the price for everything - systems, expansion units, modules, boxed items, mice, joysticks, keyboards, software, developer binder and domain and more all for $4,000. First person who replies directly to me - curt(at)atarimuseum(dot)com gets it all, so email me and let me know, thanks... Curt
