I'm trying to construct the KISS programmer
(http://www.ee.oulu.fi/~lapi/KissPIC/)  for my PowerMac clone (powerbase).

Anyone have any experience with this project - Any gotcha's to keep from
frying my mac?

1). re: The serial port connections in the circuit - are these the way they
should be connnected to the female 8pin DIN on the pcb or should any of
these lines be reversed to match the Mac's output.

2). My powersupply will be an old surplus "brick" 12VDC that is actually
putting out about 14.2 volts. I was going to add a 660 ohm resistor to bring
the voltage down to 13 - 13.5. Any flaws with that idea?

3). Any way to test the serial ports before I put power on this thing to
prevent the wrong flow of electrons into my Mac?

As you can see, I know very little about electronics and any help would be
appreciated.  Thank You.
