Just posted a bunch of stuff over in the Marketplace forum for sale, and some freebies (just pay shipping). I really need to slim down my collection and I just bought another lot of stuff last weekend... kept the stuff I needed and passing the rest on.

I also have a pretty good selection of Compute! books, but I'm unsure what to do with them... I will need to sell them, but I don't know really what they are worth, so I was thinking eBay and let the market decide. The pictures are roughly how I thought I'd split the lots up.
The collection that I bought was mainly programming stuff and magazine disks (copies mainly), but there was some original software that I imaged. TeleTari and The Bookkeeper being two notable ones that don't seem to be on Atarimania. Interestingly, The Bookkeeper (from 1982) has copy protection (sector 365 is missing from two of the disks-and is checked for during boot). There is some interesting other stuff that I found, for instance a program called XL2 by a local (to me) Atari guy, John K. Picken. I never heard of this software before, but it's like the snapshot software that Tom Hunt created and allows you to have two complete computer images running at the same time and you can switch between them.
