[NTLK] Jim's dead Newton

[Woody Smith]

As I recall the replacement of a ROM board will also remove any system patches. I once used a 2x00 ROM to remove the factory system patch on an eMate that changes it’s system I’d from 2.2 to 2.1

It's true that I often use this manipulation to put a Watson ROM in a Newton 200, because there is no place to connect the Interconnect dongle on the Watson, the shell prevents it. So I would have to remove the Watson every time I want to connect it to my Macs. So, since the Watson is disassembled, I put its ROM in a 2000, the one I use for my tests, just to protect the Newton part of this Watson.
