The SPI port will use the same type of header pins as used for jumpers, yes? As I recall, there will be a jumper or switch to write protect the PROM. If that uses the same type of header pins as the SPI, you avoid having an additional type of part. At this point additional pins do not add a new part type. Pins only require a shorts and opens test, and can be automatically tested, assuming a bed-of-nails type fixture. With a card edge fixture, you'd need a cable plugged into the pins. Switches, whether DIP or the hex type with up and down buttons, are more user friendly, and someone posted that the prices are lower than for pins. But it may well be that the testing costs for switches outweighs the parts cost. And a switch can't be used for the SPI port, so that is an additional type of part. > (esp. for hand-assembled through-hole parts) They haven't figured out how to machine assemble pins yet?

Whoever installs the board in a computer is responsible for verifying the correct settings of jumpers/switches for their application.
