Does anyone out there know how to configure an AT&T 6300 to use a
video card external to what is onboard? I know there is an additional
ega card, but is there some means to override the onbard
monochrome/clor graphics video output circuits and use a standard
monochrome card, hercules color card, etc. I have an application that
MUST use the monochrome & color graphics video output simultaneously.
(Please don't tell me that it can't be done, I know it has to be able to be
done somehow...) Thanks in advance.

Iurilli Bell Communications Research Piscataway, NJ > {allegra, ihnp4, topaz}!rruxqq!pat The following notes I saved from the net awhile back may help you: "To put in another graphics board you must first disable your present board. To do this you remove a 74LS00 chip located on the bottom middle of the graphics board. It is above where the +5 volts and ground wire connect. In newer machines it is in a socket on older ones it is soldered in. NOTE this will void your warranty if you do it yourself! After removing the chip then pins 7&6 must be jumpered together and 3,8,11,14 must all be tied together. We got this fix directly from AT&T. We just bought 300 of these units and some will be modified." John N. Le (AT&T IS/CPL Indpls, IN) ihnp4!inuxh!jnl PS: No disclaimer.... redirect any flames to /dev/null.
