Some people want absolutely factory original. Others want a maxed-out example. Maybe you can find someone who has a vanilla 512k who will swap boards with you. That would give him a stock-looking 512k that works like a Plus, which is a much more useful Mac. The Mac you have now is a pretty good upgrade, and is a lot rarer than a stock 512 or 512e. For the Mac cognoscenti, you can show off the upgrade. The general populace won't know the difference and won't be impressed anyhow. :beige:
