But then how many true Amigans are running A1200's with just their stock processors?
Me!
Well, not really. It's a secondary machine and I'm just waiting for the right upgrade to wander along.
And techinically, I'm not even running it right now. It's missing, ironically enough, a floppy drive!
As to the issue at hand, I'd check what revision motherboard each machine has before making a decision on selling.
