Thanks for the responses!
Dmitry, that is what I want to do my Adam soon (program), I am looking to move soon, so it will be after that, but I really do love that system.
Atari 800XL with VBXE card sounds like the way to go. I was doing some more research and what does everyone think of the 130XE, that was the last 8-bit computer from Atari correct? They are a little cheaper on ebay (blah) and if they are move powerful or better to upgrade, maybe that would be the way to go?
Paul, thank you for pointing me to your website now, I am looking at what you have to offer!
