I programmed a 12F629 and inserted it into my breadboard and it works fine, so I put it on my perfboard in a socket and it will not work, it has an internal oscillator so my connections are only voltage supply and ground, no other connections to the ports, the program simply turns a port on high when I apply a high to to an input. I took it out put it in the breadboard again and it works, I'm just using a logic probe at this point although on the breadboard it lights the LED if I hook it up. I'm baffled, I even made a second board thinking there was a strange issue with the first, still no go, I'm using two boards, one is perfboard the other is Radio Shacks Archer experimenter board made for TTL, neither one will work. No shorted or open pins, voltage and ground are on the pins of the chip, what could cause this??? much appreciated if I can get any help with this.
