So I finally picked up a dirty unloved 128k Mac on eBay for $200 - a crazy price, but what the hell.

Anway, turns out it has a Macs-a-Million upgrade installed which involves a bunch of soldering, Mac Plus ROM chips etc

What would you do? Try and remove the upgrade and restore it to stock or keep it as-is?

I'd need to find some 64k ROM's of course...
