Just in case you don't have a data book, it's a single chip microcontroller.
2k x 8 EPROM
128 x 8 RAM
1 to 11 MHz clock
typ 95mA total supply current
These chips don't have a "security fuse" (I think this concept is substantially
newer than the 8048/8049 series chips - they've been around 10 years or more) so
there ought to be no problem with uploading its contents. Provided, of course,
that you have a suitable programmer :-)
