Okay cool!  :)

Now I have another question:  Any advise for programming two 8-bit
EPROMS with a program for, say, a 68000 CPU?  It's a 16-bit CPU with a
32-bit address bus; I'd like to use two 8-bit EPROMS for it's program
memory.  Is it possible for me to make, perhaps, an "even" and an "odd"
chip?  (I've got an EMP-10 programmer by Needhams...)

Cheers,
