Are you sure about that? This is the first I've ever heard of any issues
upgrading either model MP120.
Remember, the "1MB" MP120 had about 640k of DRAM with the rest being
flash. The 2MB version had ~1.4MB of flash and the same 640k of DRAM. The
OS 1.x ROMs were all 4MB; the OS 2.x ones are 8MB.

The ExpertPad/OMP/MP100 also had a different (more vertical
pixels) LCD. The MP110 changed to a more standard LCD panel for cost
savings, I believe.
If you don't have hot air rework experience, don't even _think_ about
attempting this - only the MP120 and onwards had socketed ROMs.
The only way this would work is if Apple, in designing the Newton ROM,
decided to make it work. They might have - you might be lucky.
