How can I program the ROM of a MOS 6530?

I downloaded the 6530 datasheet from the 6502 datasheet archive. As I thought, the ROM is mask programmed. That means it was programmed during manufacturing and cannot be reprogrammed. There are a few other options that were mask programmed also. You might want to look over the datasheet for all of the specifics. Here is the link:

As 8bit said, the ROM is programmed during production. This site: http://www.baltissen.org/htm/buildkim.htm tells you how to reproduce a Commodore KIM using normal available IC's. In this case a 6530 can be replaced by a 6532 and an EPROM.
