Correct.  there is a serial number thats easy to take care of
but the real problem is that MOVCPM has to be valid for the BIOS
in use.  Reason is that MOVCPM is a relocator that operates by
adjusting the various Jumps and Calls in the code and if the 
BIOS and MOVCPM do not match that reloc will make hash of the 
BIOS.

Likely less for a lot of reasons. Roms can be mapped out of the 
ram map or transient. 

I'd bet more like 56K is the case.

Good idea and then if you sysgen that code to a disk use a fresh 
disk to avoid crunching a working one.
