Hello All, I am a young professional electrical engineer who has just started working in Automation field. We build customized panels including PLCs, HMIs, Pushbuttons, Lights, Relays etc., I have been searching for a reference codes and standards that can be helpful for designing and wiring...

I was wondering what would be required, or if its possible, to extract an existing program from an EPROM NEC D27128D? I use Microchip PICs and a PicStart Plus, but I doubt its compatible. I also realise the output might be in hex, but any helpful clues would be useful.
