I just finished spending a couple of months (and a LOT of money) rehabbing an old A2000 I got off of eBay. Don't know if you're ready for this, but restoring an A2000 is a time-consuming and expensive project, espeically if you want to bring it up to a spec of usability compatible with today's standards. That definitely means a web browser and a network device of some type,a CD player, and most likely video card accelerator and CPU/RAM/SCSI controller and accelerator. These items are not cheap. And, most importantly, look at the battery, and remove it! More than likely, its leaking, and slowing eating up your motherboard.
Later on, after you've added what I consider the basics, you may want to got for a sound device and other coolities. (See the spec list on my machine). Good luck! 8-)
