One of the ROMs is a different part number,  which gives slightly different 
default screen colors,  but I know that in repairing one the ROM out of a C64 
can also be used.  There are also differences in the drive,  for sure,  but 
it's been long enough since I've been into one that I don't remember what 
those are off the top of my head.  I do have a service manual for those 
around here someplace,  I used to fix them,  along with a lot of other C= 
stuff...

Anybody looking for any c= parts?  Drop me a note off-list.
