Hello everyone, I have the UPA-USB programmer v1.3 red plate. Today I tested the NEC adapter for the first time. My surprise that if I try to read only with upa, it tells me that there is no device, but if I add the adapter, alone or connected to the chip it gives me the error "vcc / vdd out range". From there I do not take it out. In theory it is the same one that appears in the pdf manual of the UPA, it has an AT28c16 chip, I have seen others with the AT29c010. I do not understand why when putting an adapter it does not do anything.
Did someone happen to him the same?
a greeting
