 		 #112251 - oh well, wrong again
Responding to: ???'s previous message
Save This Code
/PSEN  /WR  /OE
  0     0     0 (don't care, as it should not happen, actually)
  0     1     0
  1     0     0
  1     1     1
This doesn't sound like a NOR to me.

oh well, you are wrong again - what you describe is, a negative OR (any low in = low out)

I you want to use DeMorgan, it goes for an AND:
A * B = C (positive AND)
!!A * !!B = !!C (still positive AND)
!(!A + !B) = !!C
(!A + !B) = !C
!A + !B = !C (negative OR)
