Oh, I see. Not as simple as I thought. So it would require total 
disassembly. I might as well just look into getting a replacement screen, 
rather then maybe messing up my one good MP2000. (Life w/o a MP2000 would
be pretty boring.)

How different?
Looking at the detailed picture here in step 27:

the 2 chips on my main logic board are a few mm closer to the ROM board 
socket. Also, shiny bits are above the 2 chips. ("Above" means on the 
opposite side of the black ROM board connector. These circumlocutions are 
symptomatic of my spending money on old gadgets instead of new cameras.)
