The EEprom programmer software supports the following devices 28C16, 28C256, 28C17, 29C256, 28C64. Diode D1 and resistor R1 provide the VDD isolation when programming the 24 pin devices. The jumper J3 must be shorted for 24 pin devices, and open circuit for 28 pin device programming. Following EEPROMs are pin compatible with their EPROMs version,
28C16 ---> 2716, 28C64 ---> 2764, 29C256 ---> 27256.
