Yes, but from the point of view of a purist or a museum specimen, 
alterations are not really on, so the ram board, different membrane and 
poking holes etc in the case are a non no, I guess you would need 2, one 
that is working and one that is original.

One thing I did notices was that all the interface 1's I had no longer 
worked. the drives spin and nothing happens.
 Not sure if I have any left now.

As for the gate arrays on the Amstrad, I had to get somebody to change a 
couple of those and it was quite a pain.
