Why not use optoisolators in each of the programming lines.   That way,
no mains power could enter the programmer, computer or operator.

Subject: [PIC] Standalone (pushbutton) programmer

I'm looking for a standalone, pushbutton programmer for the 16HV610, or
perhaps something that's well on the way.

The product is a dense mains powered board and pretty much any
production fault could potentially put mains onto the programmer, so I'd
rather sacrifice a few programmers than have an external PC and
sacrifice a few operators.

There are a few options that go some of the way like Olin's USBProg or
ICD2, but I'd still have to add on a board to send commands, data, etc.
In which case, it's a similar effort to build a programmer.

Steve.
