I've recently begun the search to recover the gear from my youth. I mean how can the founder of the new KC-ACE not have a working Atari computer?  I am primarily looking for an 800XL, and I've got a couple leads. My biggest unknown at this point is whether to go with original disk drive or one of the myriad of SIO solutions which would make loading files much easier, not to mention storage.  Then there is the display and other interface options I need to consider.  What I've learned, is that there are so many options, I need to learn a little more before pulling the trigger.   Any suggestions from anyone here?
