Machine control software is often stored in read only memories (ROMs) which are plugged into sockets on a circuit board. Because the software code sometimes changes after product introduction, it is often necessary to change these ROMs in the field. Since there are often several ROMs on a circuit board, it becomes a problem to get the ROM containing the correct revision and code sequence plugged into the correct socket. While this problem can be solved by using color or mechanically coded ROMs, this adds additional unwanted processing and handling costs.
