Hi
 It had some hardware to decode memory blocks and also
it had 286 like shift instructions. The interrupt table
was assigned at zero memory and had some incompatibilities
with DOS interrupts that were software interrupts.
It often had build in serial as well.
It was primarily intended for the embedded market but
it was used in some of the personal machines.
