> Does the PS+ perform verify over the full Vcc range ? > (As a "production programmer" does ?) Nope, it's a prototype programmer. But I guess in a pinch you could use a bench supply to do a multiple-vcc verification. But combined with code protection this becomes a bit tedious. IMHO the prototype-production distinction is not so hot any more with the flash PICs. When you use a (flash) PIC for let's say a Mars rover you might of course feel different.
