From the project
Adapter for using a standard JDEC 28/32 pin EPROM/EEPROM to replace a 23xx Rom
This is a rework of the excellent design made by Jim Brain to replace a 23xx ROM with a standard JEDEC 28 or 32 pin EPROM/EEPROM or Flash ROM. The main difference, this version is 1.9mm smaller in width and more centered on the socket, allowing enough spacing to replace all three roms in a C64 long-board version where Jim's is a little bit too large to install two side by side.
