        This is just speculation, but when the Mac was designed the
concept was "computing appliance".  They wanted something that would
be about the computer equivalent of a toaster to operate.  So they
neglected to support hard disks ( no HFS ), provided no expansion
capability, and gave programrs access to the entire instruction set,
since they would never need the supervisor mode to do multitasking!
Things have changed!
