I have some older circuits (from the '80) that I would like to build. The logic chips are still available. I have one that uses 8-4164 drams and one that uses 2-41464 drams. I can expand the ram the circuits uses to make them faster. If I swap the 4164's with 41256's will that work? Or if I swap the 41464's with 414256's will that work?
Thank you for helping me out with any info.
Thanks, Sky King
