I have a version of VisiCalc that comes with a PROM, but I have been 
able to use a copy of the software I created without use of the PROM.  
It's a disk version that works only on a 2040 drive so it might be an 
older version and the PROM's purpose was not copy protection.  It's also 
possible that I did not get far enough into testing to uncover the point 
where the PROM was needed.
