The 68000 family is famous for throwing out multi-processing and/or virtual
memory with the TAS instruction. Why is there a 68010??? So it can handle
virtual memory. The 68020 also has a few gothca instructions for
multiprocessing. Also, anything that mucks multiprocessing mucks DMA that
makes assumptions. Thats life in the Motorola world. Basically, you just have
to ignore the TAS instruction for machines like the Amiga. L. B. Daniel
