                         Adapter Pin Out Diagram

  I have a XT-Clone (8088) with a serial printer port.  The printer I use
is a Gemini 10x with a (36 pin) Centronics connector (that I'll be happy to
trade for a Laser Jet). :)

  The following diagram was made using a VOM.  I did a continuity test on
a factory made DB-25 to 36 pin Centeonics adapter cable to construct an
adaptor cable for my own use.

**************************************************************************
 DISCLAIMER:
  I have used the home made adaptor for 9 mos. trouble free.  However, I
accept no liability for damages caused to person(s) or property that may
result from use of this diagram.

Pins 18,21 are not used on the             Pins 15,16,17,18,21,22,23,24,26,
     on the DB-25 connector.                    28,32,34,35 are not used on
                                                the Centronics connector.
