I've obtained some 27c160,does anybody have an 16bit adapter schematic, or can anybody tell me how to wire it UP exacly? I need to write 27c160 only. Some Time ago i've borrowed an 16bit adapter without any buffers and it worked well, errors at verification were occasionally. I'm asking cause i cant find it nowhere in the web, too much garbage sites.
