It did have an x86 board and CPU, but it was not used for instruction emulation - only for support and *some* I/O functions. There was no P390 chip or board. There was often some confusion because the MP3000 used the same box as the earlier Integrated Server (IS) which was indeed just a large packaging of a P390E.
