#119767 - you posted that interrupt DOES occur:
Responding to: ???'s previous message
My case is a interrupt, which never occurs.

you posted that interrupt DOES occur:
Thus if KBPATN 0x22
KBMASK = 0x00
KBCON = 0
0x22 int
0x00 no int
0x02 int
0x20 int

so, it seems to me, that either yout keys do not pull up, but down (as most often is the case) OR that the KBI is based in the complement.

   More details.            01/01/70 00:00      
      I have never used KBI, it serves no purp            01/01/70 00:00

                        so, you have an ICE, great            01/01/70 00:00      
                           ICE could affect KBI            01/01/70 00:00      
                              How is your P0 set up            01/01/70 00:00      
                                 forget it            01/01/70 00:00
