To use a 27C128, you need 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 rom files (each 8kB) in the 16kB eprom. -You can buy the adapter here: -https://restore-store.de/ - +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.
