Responding to: ???'s previous message
Oring two lows as in the case above (!PSEN and !RD) is commonly referred to as a "negative or"

so to say what Michael show above in words

a positive and gate is also a negative or gate
a positive or gaste is also a negative and gate
a positive nand gate is also a negative nor gate
a positive nor gate is also a negative nand gate.

As with numbers the 'positive' is only included in a statement when needed for clarity.

I wholehardedly and totally agree with Michael that callingt a negative OR anything else is incorrect and
