Intel 8048
     
         The {microcontroller} used in {IBM PC} keyboards.
        The 8048 was inspired by, and similar to, the {Fairchild F8}
        microprocessor but, being a microcontroller, was designed for
        low cost and small size.  The 8048 has a modified {Harvard
        architecture}, with program {ROM} on chip and 64 to 256 bytes
        of {RAM} also on chip.  I/O is mapped in its own {address
        space}.
     
        Though the 8048 was eventually replaced by the very popular
        but bizarre {Intel 8051} and {Intel 8052}, even in 2000 it is
        still very popular due to its low cost, wide availability, and
        development tools.
     
        [Was it really _the_first_ microcontroller?  Are the ROM and
        RAM both on-chip?]
