- Well, according to the ISO standard I have in front of me, for the
- single ended connector using that is erroneously called a 50-pin
- Centronics (it is really an Amphenol "57" series), contacts 1-12, 14-25
- are ground, also contacts 35-37, 39-40, 43. The standard of course
- doesn't tell me what contacts of a DB25 that Apple chose to connect to
- what, as it isn't standard. Not only that, it isn't advisable these
- days with the fast logic on the drives necessary to get the higher speeds.
