For sale is a 2364 EPROM adapter which converts the readily available 27Cxxx to the 2364 which is used in the Commodore 64.
This adapter is suitable for C64/128 and 1541 ROM replacement. Other retro computers might need another type of adapter. (CE Line on the W27C512 EPROM has been tied LOW. CE from the 2364 is connected to OE on the W27C512 EPROM)
Address lines A13, A14, A15 have been tied how so if you use any EPROM larger than a 8k, you will need to program the binary file to the upper most ROM location.
This adapter has been tested with the following EPROMs
27C64 (Program at ROM location starting at 0x0000)
27C128 (Program at ROM location starting at 0x2000)
27C256 (Program at ROM location starting at 0x6000)
27C512 (Program at ROM location starting at 0xE000)
