But I noted that it says also that pin 25 was not always connected to ground, and in the case I am recalling from 20 some years ago, the parport in question did have 5 volts on pin 25. Serendipity? As I recall, it was on the MFC-3 card in my amiga 2000 at the time. I had assumed, and of course wikipedia didn't exist in 1991, that it was SOP.
