2532/2732 EPROM Adapter
Many old pieces of equipment contain type 2532 EPROMs, which are currently difficult or impossible to obtain. If the software has to be modified or the EPROM fails, it is in principle possible to replace the EPROM with a modern 2732, but this has a different pinout. A handy hobbyist can of course make the necessary modifications to the circuit board, but it is more convenient to use an adapter board that can be fitted in place of the 2532. The main circuit board can then remain in its original state.
