Actually, it's impossible to properly test for the MMU and FPU on the 68K family as Motorola got cheap and marketed chips with faulty MMUs and FPU as MMU-less and FPU-less chips. Depending on how the MMU or FPU was faulty testing could hang the CPU. That's why most programs had separate versions of the binary for full vs EC or LC chips - you couldn't reliably tell if you had the EC or LC model of a chip.
