I picked up one of my computer books today and read
that z8000 uses one 16 bit register to hold the 7 bit
segment number and one register to hold the 16 bit
offset. The strange thing is that the segment number
is hold in position of bit 9-14 other than the bottom
half of the first register. I goggled and found
complaint about this scheme but no one explained why
it was designed so. Could somebody on the list tell me why?
