Manual EPROM Programmer The programmer devices required for programming the electrically programmable read only memories (EPROMs) are generally expensive. Here is a low-cost EPROM programmer circuit to program binary data into 2716 and 2732 EPROMs. EPROM Programmer Circuit The circuit uses timer NE555 (IC2) wired as a monostable. When push-to-on switch S1 is pressed, IC2 generates a 50ms pulse, which is given to the program pin 18 of the ZIF SOCKET through switch S2. EPROM is inserted into the Z
