This will make you able to switch between 2 rom files (each 8kB) in the 16kB eprom. +You can make the adapter into a dual rom, by a 27C128 eprom, a 4k7 - 10k ohm resistor, a wire with a 2 way switch connected to the 2 pin header. This will make you able to switch between 2 roms (each 8kB) in the 16kB eprom. -You can also use this pcb to create an adapter to read the ROM chips in the C64, simply add 2x14pin male/male sil headers in the bottom instead of the 28pin rom socket. and 24pin rom socket on top instead of the 2x12 pin sil headers in the bottom. +You can also use this pcb to create an adapter to read the ROM chips in the C64, simply add 2x14pin male/male sil headers in the bottom instead of the 28pin rom socket. and 24pin rom socket on top instead of the 2x12 pin sil headers in the bottom. Basically swap posistions of the socket and the sil haaders. ![Rom Adapter](Pics/top.png)
