Paul,

What monitor are you are using with your modified AT&T pc6300??
(I would have sent directly to you but I don't know how to mail to BITNET)

What I really want to do is use an ega card in my PC6300
(doing the modification you did) along with the AT&T color monitor
I already have. My problem is that since the AT&T color monitor has
a non standard plug, I have been unable to find an ega board
I could plug it into.

Any ideas would be greatly appreciated.
