Sorry, I was out last night so never got a chance to respond. Yes, you 
can leave the PetVet in a running PET to flash it - it's the easiest way 
to get power to it.

The four 3-pin jumpers are for programming and rom set selection, as 
described on Mike's web-site. The undocumented 2-pin header is for a 
reset switch - it's hooked directly to the 6502's reset pin.

The 6-pin header is for power, but if you power it from the motherboard 
it's not needed.
