That cable you have looks to be either the cable used to allow a PC to connect to a Displaywriter 5218 printer or the cable for the PC attachment kit to attach directly to the 6580 system. What is its pinout? Also do you have the accompanying software disk?Hi, I'm looking to understand what is a IBM DISPLAYWRITER. The cable hasn’t any label. It’s a 9-PIN- D-shell FEMALE to 25-PIN- D-shell FEMALE, long a couple of meters. Any suggestion ?Thanks in advance dor any suggestion. Giorgio - Torino- Italy
