And this is the adapter.

I helped the author redesign it to fit it into the Motronic ECU.

Of course it's needed, otherwise the chip won't latch the inputs, it uses same bus to access RAM and ROM.

So you think that every chip with same pinout operates the same?
I don't think you have any clue what I said in my last message. Maybe it's time to go back to school.

27C512 with latch adapter will work exact the same as 27C256 with latch adapter, there's zero difference between the two besides an extra address pin.
