Hi,
The ROM should work. Are you sure about pin one removal wil do the trick?
It should be tied permanently to either ground or +5V, not left just not
connected.
I am sure the pin layouts are on the web somewhere, at least in the EPROM
related articles by Elektuur in the do it yourself -magazines section of my
webpage. The EPROM in statische geheugenuitbreiding discuuses just this
subject.
