 IBM PC 340 Series 6560 and PC 100 Series 6260 machine types do                 
 not support the following IBM ISA ARTIC Communication adapters:

 IBM X.25 INTERFACE CO-PROCESSOR (512KB)                                        
                                                                                
 There is a timing incompatibility between the 6560 and 6260                    
 systems and the ARTIC adapters which prevents stable operation.
