   You don't say if the programs that crash work on an enhanced IIe, or just   
   regular IIe.  That would probably mean usage of an unsupported opcode that   
   doesn't work on enhanced machines.   
      
   I know the CALL -3100 command to enable graphics doesn't work on the Laser.    
   Not sure about the IIc.   
      
   Are we talking all programs with graphics, the ones that crash that is?  A   
   list of the programs that don't work would be handy.   
      
   Although I understand where you are going.  I had the same thought at one time   
   to install a IIe ROM into my Laser for more compatibility.   
      
   Instead of changing the ROM though, probably an easier idea might be to   
   install the enhanced ROM's software into the Laser or IIc's Auxilliary   
   Language Card, set the soft switches that puts the Auxiliary memory in control   
   and run the software from there.    
    The only time it won't work is if the programs are booted from disk.
