The point probably lies in that the programmer is able to do insertion check on every pin before it attempts to start the programming cycle. It happens quite often it says "no connection on pin xxx", repositioning of the chip into ZIF always helps.
Again I surmise If a programmer insertion checks with very low currents, it will report like the one Jan uses, if it insertion checks with slightly higher currents, it will report like mine. Mine does do insertion check, I am told every time I insert the chip backwards. erik |
