You need a programmer that can handle this part.  The Phillips/Signetics
extensions to the MCS-51 family use a _serial bitstream on the RESET pin_ to
put the part into program mode.  This is similar to many PALs, but unusual
in the EPROM/microprocessor world.  A "standard" programmer may not be
capable even with a socket adapter.
