No offense meant, but I really thought, that a PC - which is far from being cheap - has a reverse polarity protection. After all, reverse polarity can happen even with experience users, if they are in a hurry/just tired or whatever. If the battery connections are not protected, this has to be officially requested as improvement. IMHO.
He didn't say he had a PC, he has a Prizm...different boards, one of which, the PC, has a voltage regulator...the other one, the Prizm does not. It's been awhile since the development days, but if memory serves, Erv does indeed have reverse polarity protection on the PC and CF boards. Maybe if we're lucky Erv or Zook will chime in and confirm or refute me.
