"I just picked up an Apple Laserwriter II NTX which appears to be working. The problem is I need to find out what this thing has for I/O, and what the dip switch settings are. It appears to have a 50 pin centronics connector, along with a DB25, an appletalk port and one other port."
(From: Erik Johansson (erijo105@student.liu.se).)
The ports are a Phonenet Appletalk connector, a 50 pin centronics-like scsi connector (to connect a font cache hard disk), 25 pin female D-sub serial connector (wired as a DTE so the cable should be the same as when connecting to computers, not a computer and a modem) and a RS-422 8 pin miniDIN connector (also for serial communication).
The jumper settings:
