Yes, you can burn read and burn the rom from the later //c and
insert it in the earlier. I believe that peek from above should read
zero to be compatible. Check the machine you'll be taking rom
from. Also you'll need to open jumper at W1 and close the one at
W2. I think that's correct. Well switch them, whatever they are now,
make them the opposite. ;-) I did one not too awful long ago. Help
you when you're ready to do it.
