Motorola second sourced an IntEl microcontroller?  Now that's interesting.

I have a universal device programmer that can program and read 8751s in
a 40 pin DIP.  Unfortunately that won't do you any good unless you want
to pull out the chip and send it to me.  And we'd certainly want to
confirm that it would have a compatible pinout.  Also, it is possible
that there is a security fuse in there that will prevent the program
from being read out anyway.
