At the time of the EMC beginnings, there were little choices and eventually something worked well enough :). Remember the 133MHz computers we used that time?

As far as I understand it the complications are similar to convering to AMD64 support.

There was slight interest, but the neverending inflow of better and faster x86 computers made it go away.
