The original PS/2 model 30 was an 8086, I think.

I think MCA is still used in the RS-6000 series (used to be,
anyway). The *main* reason that MCA did not become a success was that
IBM wanted license fees for it. This license fee was per machine, and
even included IBM-compatible machines without MCA slots, *and* machines
shipped before the introduction of MCA.
