What does the 18F877 have to do with anything??  I think we are not 
communicating here, Olin!  :-)  So far as "like which ones," the 3013 
has 2 UART's and the 452 only has one, for example.  I think that 
probably I did not describe the problem clearly enough.  I have a board, 
which has instruments such as an RPG, an LCD, a pushbutton, some LED's, 
a temperature sensor, etc., already in place.  I called it a prototype 
board, but probably that was an ill-advised term.  The board has an 
18F452 (in a socket) which is connected to the different instruments.  
Using exactly the same physical board, I want to substitute a 3013 for 
the 452, converting the software which uses these things from 452 
assembly language to 3013 assembly language.  Now you, as a practical 
person who does practical things, might not see the value of this, I 
will freely admit that.  But I want to do it for the same reason that 
people purport to climb Mt. Everest (or so they say, anyway).

Well, yeah, but keep in mind that there really are only two important 
things in your life.  (a) You are born, and (b), you die.  In between 
these  two important events is a bunch of  time that we need to somehow 
kill.  :-)  Anyway, since no one has come up with a neat little 
store-bought gadget that does this, guess I will just have to piggyback 
a 28-pin socket on top of a 40-pin socket and start soldering. 

Thanks for your help and suggestions, as always.
