I am in the process of writing a photo essay about the Atari XL line of computers, which I grew up on, and grew to value industrial design of tremendously. I have two questions: 1. I have accumulated quite a bit of the XL line over the year or two (see photo of most of the collection: http://www.aresluna.org/atari-photos/0-overview.jpg) and after I?m done with my photography, I won?t really have a good use for them. What should I do with those machines? Is there anyone interested in grabbing this wholesale? Should I put it up on eBay? I?ve never really sold vintage computers in any capacity, so I?m curious what works and what doesn?t. 2. I am looking for contact information for Regan Cheng, who as far as I understand was responsible for the design of the 1200XL and the XL line. I would love to chat with him if possible about some of the design decisions, nuances, stories, etc. Here?s a sample of a few of the many photos I took to celebrate/highlight those machines: http://www.aresluna.org/atari-photos (And if there are any other people who contributed to the 400/800/XL/XE line as far as product design or packaging design, I would love to be connected if possible.) Thanks in advance for any help! M.
