WTD: AT&T 6300 Personal Computer mother bd dip switch map

[B. Degnan]

Hi - I am attempting to install a CGA card onto a AT&T 6300 Personal 
Computer.  It currently has only a 25-pin CRT port for a terminal dumb 
terminal (w/o keyboard).  I need the dip switch map so I can set for the 
CGA monitor.  The 6300 has a 8086 processor, and it's an OEM system from 
Olivetti.  I assume that the user's guide for the Olivetti 8086 PC would 
due equally as well.
Thanks.
