Honestly, that pile of neglect is not worth your trouble. I see you're located in Florida. I'm in Atlanta. Would you be interested in an A2000 with all the basics including 3.1 KS and hard drive in working condition for the cost of shipping?
BTW, if your friend is offering that 500 for free, take it.
Many of the parts can be used as spares in a 2000 IF they're still good.
