But 50mS isn't the default pulse width for 2716 so you can't assume that the program is correct. The program can do this for 2716, but not 2732 (longest pulse is 25mS). ![]() 27 EPROMs are specified to be programmed at VCC=5V, providing you program with a 50mS pulse. Similarly, you need to know what the appropriate programming pulse width is. Silly question, but have you got all the jumpers set correctly? I'll admit my first time out I misinterpreted the software diagram and set my jumpers to the exact opposite of how they should have been. Could be a number of things.and not something I've encountered before. ![]()
