   I compared with an enhanced //e.  I don't generally test stuff with the   
   1982 firmware.

   CALL -3100 works on the //c, meaning it has to do with differences in the   
   BASIC (as F3E4 is in BASIC space) rather than differences in the monitor.

   I haven't tested everything.  I do know Cubit is one of the problem games   
   (and it has to do with using an illegal entry point, FB81, according to   
   documentation in my replacement ][+ monitor).

   I'm sure the thought wasn't uncommon among people who have used Lasers. (I   
   first had the thought back in 1996.)

   For Cubit, you can do that with the ][ or ][+ ROM.
