Matthew D'Asaro has developed a 6540 ROM replacement. The 6540 ROMs are inside the PET / CBM computers. An original EPROM is very hard to get but the 2716 EPROM can replace it. But to make the replacement possible Matthew developed a little adapter, you can build it yourself or order a complete adapter with programmed EPROM.
