The A2000 is a nice machine, I got 2 running here and they work brilliantly

I think amigakit.com still has a kickstart 2 ROM on the site for sale that you could put in.. (Or upgrade straight to 3.1 of course.. both of my 2000s are KS3.1)
I also have the PC Emulator card (obtained recently actually) It's mostly useless unless you have some really really old PC (DOS 4) software that you might wanna run on it...
Well, I hope you have fun with it

Like I've already said, they're great machines.
