Hi all,
I'm currently in need of the Pin Outs of the video card
for the AT&T 6300. This is a DB25 connector, and I need to
attach it to a DB9 connector on a Kodak DataShow projector.
This is a device that show the screen image onto an over-head
projector. Any Help would greatly be appreciated.

You may have to season to taste for what you are driving. -- Bill Kennedy usenet {rutgers,ihnp4!killer,cbosgd}!ssbn!bill internet bill@ssbn.WLK.COM
