DETAILS FOR MAKING UP A CABLE FOR AMIGA 23-PIN VDU OUTPUT TO AMIGA VGA MONITOR

==============================================================================

END “A1” - THE AMIGA CPU OUTPUT FOR VDU MONITOR IS DB23 MALE SOCKET ON AMIGA CHASSIS

END “B1” - AMIGA MONITOR VDU INPUT IS AN IN-LINE 15-PIN RGB MALE SOCKET ON THE END OF A GROMMETED CABLE BUILT INTO THE VDU CHASSIS

 

THE CABLE TO JOIN THESE ENDS IS AS FOLLOWS

------------------------------------------

END “A2” - FEMALE DB23 PLUG
END “B2” - FEMALE VGA 15 pin = 3 rows (not 2 row D-type)
