This does exactly what you say, i. Email Required, but never shown. They can usually answer these types of questions. Sign up using Email and Password. With that resistor in series with pin 1, swapping in an 8K ROM instead of the 32K one should work just fine.
Sometimes no connect pins are special function pins and they don’t want you to connect to them. In general, except in cases where the manufacture is specifically supporting compatible footprints between different parts, you should not connect to the NC pins.

Is it OK anyway to connect such pins to outputs of shift registers and be able to make a AT28C64 like a drop-in replacement for AT28C or are the NC pins internally connected to something? And if the datasheet is not absolutely clear, contact the vendor.
For memory chips in particular, pins that get used as address pins in larger parts and are NC pins in smaller parts can usually be connected.
That’s the obvious part. Sign up using Facebook. In the future I will do many of these circuits, however I haven’t yet decided if I need the full 32KB of memory.
Well no connect could mean do not connect or does not connect. The datasheet of the AT28C64 makes it pretty clear:
